| 840 | + | |
| 841 | +## 性能优化建议 | |
| 842 | + | |
| 843 | +### 1. 分页 | |
| 844 | + | |
| 845 | +使用 `size` 和 `from` 参数进行分页： | |
| 846 | + | |
| 847 | +```json | |
| 848 | +{ | |
| 849 | + "query": "玩具", | |
| 850 | + "size": 20, | |
| 851 | + "from": 0 // 第1页 | |
| 852 | +} | |
| 853 | + | |
| 854 | +{ | |
| 855 | + "query": "玩具", | |
| 856 | + "size": 20, | |
| 857 | + "from": 20 // 第2页 | |
| 858 | +} | |
| 859 | +``` | |
| 860 | + | |
| 861 | +**建议**: | |
| 862 | +- 单页结果数不超过 100 | |
| 863 | +- 深度分页（from > 10000）性能较差，建议使用 `search_after`（未来版本支持） | |
| 864 | + | |
| 865 | +### 2. 字段选择 | |
| 866 | + | |
| 867 | +默认返回所有字段。如果只需要部分字段，可以在后端配置中设置。 | |
| 868 | + | |
| 869 | +### 3. 缓存 | |
| 870 | + | |
| 871 | +系统自动缓存： | |
| 872 | +- 查询向量（避免重复计算） | |
| 873 | +- 翻译结果 | |
| 874 | +- 常见查询结果（未来版本） | |
| 875 | + | |
| 876 | +### 4. 批量查询 | |
| 877 | + | |
| 878 | +如需批量查询，建议： | |
| 879 | +- 使用异步并发请求 | |
| 880 | +- 控制并发数（建议 ≤ 10） | |
| 881 | +- 添加请求间隔（避免限流） | |
| 882 | + | |
| 883 | +--- | |
| 884 | + | |
| 885 | +## 限流规则 | |
| 886 | + | |
| 887 | +| 端点 | 限制 | | |
| 888 | +|------|------| | |
| 889 | +| `/search/` | 无限制（生产环境建议配置） | | |
| 890 | +| `/search/suggestions` | 60次/分钟 | | |
| 891 | +| `/search/instant` | 120次/分钟 | | |
| 892 | +| `/admin/*` | 60次/分钟 | | |

| 896 | +## 常见问题 | |
| 897 | + | |
| 898 | +### Q1: 如何判断一个字段应该用哪种过滤器？ | |
| 899 | + | |
| 900 | +**A**: | |
| 901 | +- **精确匹配过滤器** (`filters`): 用于 KEYWORD 类型字段（如类目、品牌、标签等） | |
| 902 | +- **范围过滤器** (`range_filters`): 用于数值类型字段（如价格、库存、时间等） | |
| 903 | + | |
| 904 | +### Q2: 可以同时使用多个过滤器吗？ | |
| 905 | + | |
| 906 | +**A**: 可以。多个过滤器之间是 AND 关系（必须同时满足）。 | |
| 907 | + | |
| 908 | +```json | |
| 909 | +{ | |
| 910 | + "filters": { | |
| 911 | + "categoryName_keyword": "玩具", | |
| 912 | + "brandName_keyword": "乐高" | |
| 913 | + }, | |
| 914 | + "range_filters": { | |
| 915 | + "price": {"gte": 50, "lte": 200} | |
| 916 | + } | |
| 917 | +} | |
| 918 | +``` | |
| 919 | +结果：类目是"玩具" **并且** 品牌是"乐高" **并且** 价格在50-200之间。 | |
| 920 | + | |
| 921 | +### Q3: 如何实现"价格小于50或大于200"的过滤？ | |
| 922 | + | |
| 923 | +**A**: 当前版本不支持单字段多个不连续范围。建议分两次查询或使用布尔查询。 | |
| 924 | + | |
| 925 | +### Q4: 分面搜索返回的 selected 字段是什么意思？ | |
| 926 | + | |
| 927 | +**A**: `selected` 表示该分面值是否在当前的过滤器中。前端可以用它来高亮已选中的过滤项。 | |
| 928 | + | |
| 929 | +### Q5: 如何使用自定义排序？ | |
| 930 | + | |
| 931 | +**A**: 使用 `sort_by` 和 `sort_order` 参数： | |
| 932 | + | |
| 933 | +```json | |
| 934 | +{ | |
| 935 | + "query": "玩具", | |
| 936 | + "sort_by": "price", | |
| 937 | + "sort_order": "asc" // 价格从低到高 | |
| 938 | +} | |
| 939 | +``` | |
| 940 | + | |
| 941 | +常用排序字段： | |
| 942 | +- `price`: 价格 | |
| 943 | +- `create_time`: 创建时间 | |
| 944 | +- `days_since_last_update`: 更新时间 | |
| 945 | + | |
| 946 | +### Q6: 如何启用调试模式？ | |
| 947 | + | |
| 948 | +**A**: 设置 `debug: true`，响应中会包含 `debug_info` 字段，包含： | |
| 949 | +- 查询分析过程 | |
| 950 | +- ES 查询 DSL | |
| 951 | +- ES 响应详情 | |
| 952 | +- 各阶段耗时 | |

| 1002 | +## 性能优化建议 | |
| 1003 | + | |
| 1004 | +### 1. 合理使用分面 | |
| 1005 | + | |
| 1006 | +```bash | |
| 1007 | +# ❌ 不推荐：请求太多分面 | |
| 1008 | +{ | |

| 1013 | + // ... 10+ facets | |
| 1014 | + ] | |
| 1015 | +} | |
| 1016 | + | |
| 1017 | +# ✅ 推荐：只请求必要的分面 | |
| 1018 | +{ | |
| 1019 | + "facets": [ | |
| 1020 | + {"field": "categoryName_keyword", "size": 15}, | |

| 1022 | + ] | |
| 1023 | +} | |
| 1024 | +``` | |
| 1025 | + | |
| 1026 | +### 2. 控制返回数量 | |
| 1027 | + | |
| 1028 | +```bash | |
| 1029 | +# ❌ 不推荐：一次返回太多 | |
| 1030 | +{ | |
| 1031 | + "size": 100 | |
| 1032 | +} | |
| 1033 | + | |
| 1034 | +# ✅ 推荐：分页查询 | |
| 1035 | +{ | |
| 1036 | + "size": 20, | |
| 1037 | + "from": 0 | |
| 1038 | +} | |
| 1039 | +``` | |
| 1040 | + | |
| 1041 | +### 3. 使用适当的过滤器 | |
| 1042 | + | |
| 1043 | +```bash | |
| 1044 | +# ✅ 推荐：先过滤后搜索 | |
| 1045 | +{ | |
| 1046 | + "query": "玩具", | |
| 1047 | + "filters": { | |
| 1048 | + "categoryName_keyword": "玩具" | |

| 5 | +## v3.0 - API 接口重构 (2024-11-12) | |
| 6 | + | |
| 7 | +### 重大更新 | |
| 8 | + | |
| 9 | +本版本对搜索 API 进行了全面重构，移除硬编码逻辑，实现了灵活通用的 SaaS 接口设计。 | |
| 10 | + | |
| 11 | +#### ❌ 破坏性变更（不向后兼容） | |
| 12 | + | |
| 13 | +1. **移除硬编码的 price_ranges 参数** | |
| 14 | + - 旧方式：`filters: {"price_ranges": ["0-50", "50-100"]}` | |
| 15 | + - 新方式：`range_filters: {"price": {"gte": 50, "lte": 100}}` | |
| 16 | + | |
| 17 | +2. **移除 aggregations 参数** | |
| 18 | + - 旧方式：`aggregations: {"category_stats": {"terms": {...}}}`（ES DSL） | |
| 19 | + - 新方式：`facets: [{"field": "categoryName_keyword", "size": 15}]`（简化配置） | |
| 20 | + | |
| 21 | +3. **响应格式变更** | |
| 22 | + - 旧方式：`response.aggregations`（ES 原始格式） | |
| 23 | + - 新方式：`response.facets`（标准化格式） | |
| 24 | + | |
| 25 | +#### ✅ 新增功能 | |
| 26 | + | |
| 27 | +1. **结构化过滤参数** | |
| 28 | + - 新增 `range_filters` 参数：支持任意数值字段的范围过滤 | |
| 29 | + - 支持 `gte`, `gt`, `lte`, `lt` 操作符 | |
| 30 | + - 示例： | |
| 31 | + ```json | |
| 32 | + { | |
| 33 | + "range_filters": { | |
| 34 | + "price": {"gte": 50, "lte": 200}, | |
| 35 | + "days_since_last_update": {"lte": 30} | |
| 36 | + } | |
| 37 | + } | |
| 38 | + ``` | |
| 39 | + | |
| 40 | +2. **简化的分面配置** | |
| 41 | + - 新增 `facets` 参数：替代复杂的 ES DSL | |
| 42 | + - 支持简单模式（字符串数组）和高级模式（配置对象） | |
| 43 | + - 示例： | |
| 44 | + ```json | |
| 45 | + { | |
| 46 | + "facets": [ | |
| 47 | + "categoryName_keyword", // 简单模式 | |
| 48 | + {"field": "brandName_keyword", "size": 15} // 高级模式 | |
| 49 | + ] | |
| 50 | + } | |
| 51 | + ``` | |
| 52 | + | |
| 53 | +3. **标准化分面响应** | |
| 54 | + - 统一的分面结果格式 | |
| 55 | + - 包含 `field`, `label`, `type`, `values` | |
| 56 | + - `values` 包含 `value`, `label`, `count`, `selected` | |
| 57 | + - 示例： | |
| 58 | + ```json | |
| 59 | + { | |
| 60 | + "facets": [ | |
| 61 | + { | |
| 62 | + "field": "categoryName_keyword", | |
| 63 | + "label": "商品类目", | |
| 64 | + "type": "terms", | |
| 65 | + "values": [ | |
| 66 | + {"value": "玩具", "label": "玩具", "count": 85, "selected": false} | |
| 67 | + ] | |
| 68 | + } | |
| 69 | + ] | |
| 70 | + } | |
| 71 | + ``` | |
| 72 | + | |
| 73 | +4. **新增搜索建议端点**（框架） | |
| 74 | + - `GET /search/suggestions`: 自动补全 | |
| 75 | + - `GET /search/instant`: 即时搜索 | |
| 76 | + - 注：暂未实现，仅返回框架响应 | |
| 77 | + | |
| 78 | +#### 🔧 代码改进 | |
| 79 | + | |
| 80 | +1. **后端模型层** (`api/models.py`) | |
| 81 | + - 新增 `RangeFilter` 模型 | |
| 82 | + - 新增 `FacetConfig` 模型 | |
| 83 | + - 新增 `FacetValue` 和 `FacetResult` 模型 | |
| 84 | + - 更新 `SearchRequest` 和 `SearchResponse` | |
| 85 | + | |
| 86 | +2. **查询构建器** (`search/es_query_builder.py`) | |
| 87 | + - **完全移除** 硬编码的 `price_ranges` 逻辑（第 205-233 行） | |
| 88 | + - 重构 `_build_filters` 方法，支持 `range_filters` | |
| 89 | + - **删除** `add_dynamic_aggregations` 方法 | |
| 90 | + - 新增 `build_facets` 方法 | |
| 91 | + | |
| 92 | +3. **搜索执行层** (`search/searcher.py`) | |
| 93 | + - 更新 `search()` 方法签名 | |
| 94 | + - 新增 `_standardize_facets()` 方法 | |
| 95 | + - 新增 `_get_field_label()` 方法 | |
| 96 | + - 更新 `SearchResult` 类 | |
| 97 | + | |
| 98 | +4. **API 路由层** (`api/routes/search.py`) | |
| 99 | + - 更新所有搜索端点 | |
| 100 | + - 新增 `/search/suggestions` 端点 | |
| 101 | + - 新增 `/search/instant` 端点 | |
| 102 | + | |
| 103 | +5. **前端代码** (`frontend/static/js/app.js`) | |
| 104 | + - 更新状态管理，添加 `rangeFilters` | |
| 105 | + - 完全重写 `displayAggregations` 为 `displayFacets` | |
| 106 | + - 更新过滤器处理逻辑 | |

| 124 | + | |
| 125 | +#### 📋 迁移指南 | |
| 126 | + | |
| 127 | +**旧接口** → **新接口** | |
| 128 | + | |
| 129 | +1. **过滤器迁移**： | |
| 130 | + ```json | |
| 131 | + // 旧 | |
| 132 | + {"filters": {"price_ranges": ["50-100"]}} | |
| 133 | + | |
| 134 | + // 新 | |
| 135 | + {"range_filters": {"price": {"gte": 50, "lte": 100}}} | |
| 136 | + ``` | |
| 137 | + | |
| 138 | +2. **聚合迁移**： | |
| 139 | + ```json | |
| 140 | + // 旧 | |
| 141 | + { | |
| 142 | + "aggregations": { | |
| 143 | + "category_stats": { | |
| 144 | + "terms": {"field": "categoryName_keyword", "size": 15} | |
| 145 | + } | |
| 146 | + } | |
| 147 | + } | |
| 148 | + | |
| 149 | + // 新 | |
| 150 | + { | |
| 151 | + "facets": [ | |
| 152 | + {"field": "categoryName_keyword", "size": 15} | |
| 153 | + ] | |
| 154 | + } | |
| 155 | + ``` | |
| 156 | + | |
| 157 | +3. **响应解析迁移**： | |
| 158 | + ```javascript | |
| 159 | + // 旧 | |
| 160 | + data.aggregations.category_stats.buckets.forEach(bucket => { | |
| 161 | + console.log(bucket.key, bucket.doc_count); | |
| 162 | + }); | |
| 163 | + | |
| 164 | + // 新 | |
| 165 | + data.facets.forEach(facet => { | |
| 166 | + facet.values.forEach(value => { | |
| 167 | + console.log(value.value, value.count); | |
| 168 | + }); | |
| 169 | + }); | |

| 1 | +# Facets 类型优化总结 | |
| 2 | + | |
| 3 | +## 问题描述 | |
| 4 | + | |
| 5 | +ES查询中的 aggs（聚合/分面）返回为空，原因是数据类型不一致： | |
| 6 | + | |
| 7 | +- `SearchResponse.facets` 定义为 `List[FacetResult]`（Pydantic 模型） | |
| 8 | +- `Searcher._standardize_facets()` 返回 `List[Dict[str, Any]]`（字典列表） | |
| 9 | +- 虽然 Pydantic 可以自动转换字典到模型，但这种隐式转换可能失败或出现问题 | |
| 10 | + | |
| 11 | +## 解决方案 | |
| 12 | + | |
| 13 | +**采用"类型一致性"原则**：从数据源头就构建正确的类型，而不是依赖运行时的隐式转换。 | |
| 14 | + | |
| 15 | +### 修改内容 | |
| 16 | + | |
| 17 | +#### 1. `/home/tw/SearchEngine/search/searcher.py` | |
| 18 | + | |
| 19 | +**导入 Pydantic 模型**： | |
| 20 | +```python | |
| 21 | +from api.models import FacetResult, FacetValue | |
| 22 | +``` | |
| 23 | + | |
| 24 | +**修改 `SearchResult` 类**： | |
| 25 | +- `facets` 参数类型从 `Optional[List[Dict[str, Any]]]` 改为 `Optional[List[FacetResult]]` | |
| 26 | +- `to_dict()` 方法中添加模型序列化： | |
| 27 | + ```python | |
| 28 | + "facets": [f.model_dump() for f in self.facets] if self.facets else None | |
| 29 | + ``` | |
| 30 | + | |
| 31 | +**修改 `_standardize_facets()` 方法**： | |
| 32 | +- 返回类型从 `Optional[List[Dict[str, Any]]]` 改为 `Optional[List[FacetResult]]` | |
| 33 | +- 直接构建 `FacetValue` 对象： | |
| 34 | + ```python | |
| 35 | + facet_values.append(FacetValue( | |
| 36 | + value=value, | |
| 37 | + label=str(value), | |
| 38 | + count=count, | |
| 39 | + selected=value in selected_values | |
| 40 | + )) | |
| 41 | + ``` | |
| 42 | +- 直接构建 `FacetResult` 对象： | |
| 43 | + ```python | |
| 44 | + facet_result = FacetResult( | |
| 45 | + field=field, | |
| 46 | + label=self._get_field_label(field), | |
| 47 | + type=facet_type, | |
| 48 | + values=facet_values | |
| 49 | + ) | |
| 50 | + ``` | |
| 51 | + | |
| 52 | +## 优势 | |
| 53 | + | |
| 54 | +### 1. **类型安全** | |
| 55 | +- 静态类型检查工具（如 mypy）可以捕获类型错误 | |
| 56 | +- IDE 提供更好的代码补全和类型提示 | |
| 57 | + | |
| 58 | +### 2. **早期验证** | |
| 59 | +- 数据问题在构建时立即发现，而不是等到 API 响应时 | |
| 60 | +- 如果数据不符合模型定义，会在 `_standardize_facets()` 中抛出明确的错误 | |
| 61 | + | |
| 62 | +### 3. **避免隐式转换** | |
| 63 | +- 不依赖 Pydantic 的运行时转换逻辑 | |
| 64 | +- 减少因 Pydantic 版本差异导致的行为变化 | |
| 65 | + | |
| 66 | +### 4. **代码清晰** | |
| 67 | +- 意图明确：代码明确表示返回的是 Pydantic 模型 | |
| 68 | +- 易于维护：后续开发者能清楚理解数据流 | |
| 69 | + | |
| 70 | +### 5. **性能优化** | |
| 71 | +- 避免 Pydantic 在 API 层的重复验证 | |
| 72 | +- 减少一次数据转换过程 | |
| 73 | + | |
| 74 | +## 兼容性 | |
| 75 | + | |
| 76 | +此修改**完全向后兼容**： | |
| 77 | + | |
| 78 | +1. **API 接口不变**：`SearchResponse` 模型定义保持不变 | |
| 79 | +2. **序列化行为不变**：`to_dict()` 仍然返回字典，供需要字典格式的代码使用 | |
| 80 | +3. **数据结构不变**：FacetResult 和 FacetValue 的字段定义没有改变 | |
| 81 | + | |
| 82 | +## 测试建议 | |
| 83 | + | |
| 84 | +### 单元测试 | |
| 85 | +```python | |
| 86 | +def test_standardize_facets_returns_models(): | |
| 87 | + """测试 _standardize_facets 返回 FacetResult 对象""" | |
| 88 | + searcher = create_test_searcher() | |
| 89 | + | |
| 90 | + es_aggs = { | |
| 91 | + "categoryName_keyword_facet": { | |
| 92 | + "buckets": [ | |
| 93 | + {"key": "玩具", "doc_count": 100}, | |
| 94 | + {"key": "益智玩具", "doc_count": 50} | |
| 95 | + ] | |
| 96 | + } | |
| 97 | + } | |
| 98 | + | |
| 99 | + facet_configs = ["categoryName_keyword"] | |
| 100 | + | |
| 101 | + result = searcher._standardize_facets(es_aggs, facet_configs) | |
| 102 | + | |
| 103 | + assert isinstance(result, list) | |
| 104 | + assert isinstance(result[0], FacetResult) | |
| 105 | + assert isinstance(result[0].values[0], FacetValue) | |
| 106 | +``` | |
| 107 | + | |
| 108 | +### 集成测试 | |
| 109 | +```python | |
| 110 | +def test_search_with_facets_returns_correct_type(): | |
| 111 | + """测试搜索返回正确的 facets 类型""" | |
| 112 | + result = searcher.search( | |
| 113 | + query="玩具", | |
| 114 | + facets=["categoryName_keyword", "brandName_keyword"] | |
| 115 | + ) | |
| 116 | + | |
| 117 | + assert result.facets is not None | |
| 118 | + assert isinstance(result.facets[0], FacetResult) | |
| 119 | + | |
| 120 | + # 测试序列化 | |
| 121 | + result_dict = result.to_dict() | |
| 122 | + assert isinstance(result_dict["facets"], list) | |
| 123 | + assert isinstance(result_dict["facets"][0], dict) | |
| 124 | +``` | |
| 125 | + | |
| 126 | +### API 测试 | |
| 127 | +```python | |
| 128 | +def test_api_facets_response(): | |
| 129 | + """测试 API 返回的 facets 格式""" | |
| 130 | + response = client.post("/search/", json={ | |
| 131 | + "query": "玩具", | |
| 132 | + "facets": ["categoryName_keyword"] | |
| 133 | + }) | |
| 134 | + | |
| 135 | + assert response.status_code == 200 | |
| 136 | + data = response.json() | |
| 137 | + | |
| 138 | + assert "facets" in data | |
| 139 | + assert isinstance(data["facets"], list) | |
| 140 | + | |
| 141 | + if data["facets"]: | |
| 142 | + facet = data["facets"][0] | |
| 143 | + assert "field" in facet | |
| 144 | + assert "label" in facet | |
| 145 | + assert "type" in facet | |
| 146 | + assert "values" in facet | |
| 147 | + | |
| 148 | + if facet["values"]: | |
| 149 | + value = facet["values"][0] | |
| 150 | + assert "value" in value | |
| 151 | + assert "label" in value | |
| 152 | + assert "count" in value | |
| 153 | + assert "selected" in value | |
| 154 | +``` | |
| 155 | + | |
| 156 | +## 最佳实践总结 | |
| 157 | + | |
| 158 | +这次修改体现了以下软件工程最佳实践： | |
| 159 | + | |
| 160 | +1. **明确类型优于隐式转换**：让代码意图清晰，减少运行时错误 | |
| 161 | +2. **早期验证**：在数据流的源头进行验证，而不是末端 | |
| 162 | +3. **单一数据表示**：避免同一数据在代码中有多种表示形式 | |
| 163 | +4. **依赖注入**：Searcher 使用 Pydantic 模型，但不创建它们的定义（定义在 api.models 中） | |
| 164 | +5. **关注点分离**：Searcher 负责业务逻辑，Pydantic 负责数据验证 | |
| 165 | + | |
| 166 | +## 后续改进建议 | |
| 167 | + | |
| 168 | +1. **添加类型检查**：在 CI/CD 中加入 mypy 静态类型检查 | |
| 169 | +2. **更新测试**：确保所有测试使用新的 `facets` 字段（而不是旧的 `aggregations`） | |
| 170 | +3. **性能监控**：对比修改前后的性能差异（预期会有轻微提升） | |
| 171 | +4. **文档更新**：更新 API 文档，强调 facets 的类型安全特性 | |

| 178 | +## 🔍 关键改进 | |
| 179 | + | |
| 180 | +### 之前的问题 ❌ | |
| 181 | + | |
| 182 | +1. **硬编码限制** | |
| 183 | + ```python | |
| 184 | + if price_range == '0-50': | |
| 185 | + price_ranges.append({"lt": 50}) | |
| 186 | + elif price_range == '50-100': | |
| 187 | + price_ranges.append({"gte": 50, "lt": 100}) | |
| 188 | + ``` | |
| 189 | + | |
| 190 | +2. **暴露 ES DSL** | |
| 191 | + ```json | |
| 192 | + { | |
| 193 | + "aggregations": { | |
| 194 | + "category_stats": { | |
| 195 | + "terms": {"field": "categoryName_keyword", "size": 15} | |
| 196 | + } | |
| 197 | + } | |
| 198 | + } | |
| 199 | + ``` | |
| 200 | + | |
| 201 | +3. **不统一的响应** | |
| 202 | + - ES 原始 buckets 结构 | |
| 203 | + - 不同聚合类型格式不同 | |
| 204 | + | |
| 205 | +### 现在的方案 ✅ | |
| 206 | + | |
| 207 | +1. **通用范围过滤** | |
| 208 | + ```json | |
| 209 | + { | |
| 210 | + "range_filters": { | |
| 211 | + "price": {"gte": 50, "lte": 200}, | |
| 212 | + "days_since_last_update": {"lte": 30} | |
| 213 | + } | |
| 214 | + } | |
| 215 | + ``` | |
| 216 | + | |
| 217 | +2. **简化的分面配置** | |
| 218 | + ```json | |
| 219 | + { | |
| 220 | + "facets": [ | |
| 221 | + {"field": "categoryName_keyword", "size": 15} | |
| 222 | + ] | |
| 223 | + } | |
| 224 | + ``` | |
| 225 | + | |
| 226 | +3. **标准化的响应** | |
| 227 | + ```json | |
| 228 | + { | |
| 229 | + "facets": [ | |
| 230 | + { | |
| 231 | + "field": "...", | |
| 232 | + "label": "...", | |
| 233 | + "type": "terms", | |
| 234 | + "values": [{"value": "...", "count": 123, "selected": false}] | |
| 235 | + } | |
| 236 | + ] | |
| 237 | + } | |
| 238 | + ``` | |

| 14 | +4. ✅ **新增** `facets` 参数（简化接口） | |
| 15 | +5. ✅ **新增** 标准化的分面响应格式 | |
| 16 | + | |
| 17 | +--- | |
| 18 | + | |
| 19 | +## 迁移步骤 | |
| 20 | + | |
| 21 | +### 第一步：更新过滤器参数 | |
| 22 | + | |
| 23 | +#### 旧代码（v2.x） | |
| 24 | + | |
| 25 | +```json | |
| 26 | +{ | |
| 27 | + "query": "玩具", | |
| 28 | + "filters": { | |
| 29 | + "price_ranges": ["0-50", "50-100"] | |
| 30 | + } | |
| 31 | +} | |
| 32 | +``` | |
| 33 | + | |
| 34 | +#### 新代码（v3.0） | |
| 35 | + | |
| 36 | +```json | |
| 37 | +{ | |
| 38 | + "query": "玩具", | |
| 39 | + "range_filters": { | |
| 40 | + "price": { | |
| 41 | + "gte": 50, | |
| 42 | + "lte": 100 | |
| 43 | + } | |
| 44 | + } | |
| 45 | +} | |
| 46 | +``` | |
| 47 | + | |
| 48 | +#### 迁移对照表 | |
| 49 | + | |
| 50 | +| 旧格式 | 新格式 | | |
| 51 | +|--------|--------| | |
| 52 | +| `"price_ranges": ["0-50"]` | `"price": {"lt": 50}` | | |
| 53 | +| `"price_ranges": ["50-100"]` | `"price": {"gte": 50, "lt": 100}` | | |
| 54 | +| `"price_ranges": ["100-200"]` | `"price": {"gte": 100, "lt": 200}` | | |
| 55 | +| `"price_ranges": ["200+"]` | `"price": {"gte": 200}` | | |
| 56 | + | |
| 57 | +### 第二步：更新聚合参数 | |
| 58 | + | |
| 59 | +#### 旧代码（v2.x） | |
| 60 | + | |
| 61 | +```json | |
| 62 | +{ | |
| 63 | + "query": "玩具", | |
| 64 | + "aggregations": { | |
| 65 | + "category_stats": { | |
| 66 | + "terms": { | |
| 67 | + "field": "categoryName_keyword", | |
| 68 | + "size": 15 | |
| 69 | + } | |
| 70 | + }, | |
| 71 | + "brand_stats": { | |
| 72 | + "terms": { | |
| 73 | + "field": "brandName_keyword", | |
| 74 | + "size": 15 | |
| 75 | + } | |
| 76 | + } | |
| 77 | + } | |
| 78 | +} | |
| 79 | +``` | |
| 80 | + | |
| 81 | +#### 新代码（v3.0）- 简单模式 | |
| 82 | + | |
| 83 | +```json | |
| 84 | +{ | |
| 85 | + "query": "玩具", | |
| 86 | + "facets": ["categoryName_keyword", "brandName_keyword"] | |
| 87 | +} | |
| 88 | +``` | |
| 89 | + | |
| 90 | +#### 新代码（v3.0）- 高级模式 | |
| 91 | + | |
| 92 | +```json | |
| 93 | +{ | |
| 94 | + "query": "玩具", | |
| 95 | + "facets": [ | |
| 96 | + { | |
| 97 | + "field": "categoryName_keyword", | |
| 98 | + "size": 15, | |
| 99 | + "type": "terms" | |
| 100 | + }, | |
| 101 | + { | |
| 102 | + "field": "brandName_keyword", | |
| 103 | + "size": 15, | |
| 104 | + "type": "terms" | |
| 105 | + } | |
| 106 | + ] | |
| 107 | +} | |
| 108 | +``` | |
| 109 | + | |
| 110 | +### 第三步：更新响应解析 | |
| 111 | + | |
| 112 | +#### 旧代码（v2.x） | |
| 113 | + | |
| 114 | +```javascript | |
| 115 | +// JavaScript | |
| 116 | +const data = await response.json(); | |
| 117 | + | |
| 118 | +// 解析聚合结果（ES 原始格式） | |
| 119 | +if (data.aggregations && data.aggregations.category_stats) { | |
| 120 | + data.aggregations.category_stats.buckets.forEach(bucket => { | |
| 121 | + console.log(bucket.key, bucket.doc_count); | |

| 123 | +} | |
| 124 | +``` | |
| 125 | + | |
| 126 | +```python | |
| 127 | +# Python | |
| 128 | +data = response.json() | |
| 129 | + | |

| 131 | +if 'aggregations' in data and 'category_stats' in data['aggregations']: | |
| 132 | + for bucket in data['aggregations']['category_stats']['buckets']: | |
| 133 | + print(bucket['key'], bucket['doc_count']) | |
| 134 | +``` | |
| 135 | + | |
| 136 | +#### 新代码（v3.0） | |
| 137 | + | |
| 138 | +```javascript | |
| 139 | +// JavaScript | |
| 140 | +const data = await response.json(); | |
| 141 | + | |
| 142 | +// 解析分面结果（标准化格式） | |
| 143 | +if (data.facets) { | |
| 144 | + data.facets.forEach(facet => { | |
| 145 | + console.log(`${facet.label} (${facet.type}):`); | |
| 146 | + facet.values.forEach(value => { | |
| 147 | + console.log(` ${value.label}: ${value.count}`); | |
| 148 | + }); | |
| 149 | + }); | |
| 150 | +} | |
| 151 | +``` | |
| 152 | + | |
| 153 | +```python | |
| 154 | +# Python | |
| 155 | +data = response.json() | |
| 156 | + | |
| 157 | +# 解析分面结果（标准化格式） | |
| 158 | +if 'facets' in data: | |
| 159 | + for facet in data['facets']: | |
| 160 | + print(f"{facet['label']} ({facet['type']}):") | |
| 161 | + for value in facet['values']: | |
| 162 | + print(f" {value['label']}: {value['count']}") | |
| 163 | +``` | |

| 329 | +## 常见问题 | |
| 330 | + | |
| 331 | +### Q1: 我的代码使用了 `price_ranges`，如何迁移？ | |
| 332 | + | |
| 333 | +**A**: 使用 `range_filters` 替代： | |
| 334 | + | |
| 335 | +```python | |
| 336 | +# 旧 | |
| 337 | +filters = {"price_ranges": ["50-100"]} | |
| 338 | + | |
| 339 | +# 新 | |
| 340 | +range_filters = {"price": {"gte": 50, "lte": 100}} | |
| 341 | +``` | |
| 342 | + | |
| 343 | +### Q2: 我使用了 ES 聚合语法，如何迁移？ | |
| 344 | + | |
| 345 | +**A**: 使用简化的 `facets` 配置： | |
| 346 | + | |
| 347 | +```python | |
| 348 | +# 旧 | |
| 349 | +aggregations = { | |
| 350 | + "my_agg": { | |
| 351 | + "terms": { | |
| 352 | + "field": "categoryName_keyword", | |
| 353 | + "size": 15 | |
| 354 | + } | |
| 355 | + } | |
| 356 | +} | |
| 357 | + | |
| 358 | +# 新（简单模式） | |
| 359 | +facets = ["categoryName_keyword"] | |
| 360 | + | |
| 361 | +# 新（高级模式） | |
| 362 | +facets = [ | |
| 363 | + {"field": "categoryName_keyword", "size": 15} | |
| 364 | +] | |
| 365 | +``` | |
| 366 | + | |
| 367 | +### Q3: 响应中的 `aggregations` 字段去哪了？ | |
| 368 | + | |
| 369 | +**A**: 已改名为 `facets`，并且格式标准化了： | |
| 370 | + | |
| 371 | +```python | |
| 372 | +# 旧 | |
| 373 | +for bucket in data['aggregations']['category_stats']['buckets']: | |
| 374 | + print(bucket['key'], bucket['doc_count']) | |
| 375 | + | |
| 376 | +# 新 | |
| 377 | +for facet in data['facets']: | |
| 378 | + for value in facet['values']: | |
| 379 | + print(value['value'], value['count']) | |
| 380 | +``` | |
| 381 | + | |
| 382 | +### Q4: 如何实现多个不连续的价格范围？ | |
| 383 | + | |
| 384 | +**A**: v3.0 不支持单字段多个不连续范围。请使用布尔查询或分多次查询： | |
| 385 | + | |
| 386 | +```python | |
| 387 | +# 方案1：分两次查询 | |
| 388 | +result1 = search(query="玩具", range_filters={"price": {"lt": 50}}) | |
| 389 | +result2 = search(query="玩具", range_filters={"price": {"gte": 200}}) | |
| 390 | + | |
| 391 | +# 方案2：使用范围分面统计（不过滤，只统计） | |
| 392 | +facets = [{ | |
| 393 | + "field": "price", | |
| 394 | + "type": "range", | |
| 395 | + "ranges": [ | |
| 396 | + {"key": "低价", "to": 50}, | |
| 397 | + {"key": "高价", "from": 200} | |
| 398 | + ] | |
| 399 | +}] | |
| 400 | +``` | |
| 401 | + | |
| 402 | +### Q5: 我需要继续使用旧接口，怎么办？ | |
| 403 | + | |
| 404 | +**A**: v3.0 不提供向后兼容。建议： | |
| 405 | +1. 尽快迁移到新接口 | |
| 406 | +2. 如果暂时无法迁移，请继续使用 v2.x 版本 | |
| 407 | +3. 参考本文档快速完成迁移（通常只需要 1-2 小时） | |
| 408 | + | |

| 441 | + | |
| 442 | +### 预期性能影响 | |
| 443 | + | |
| 444 | +| 指标 | 变化 | 说明 | | |
| 445 | +|------|------|------| | |
| 446 | +| 查询构建 | +5-10ms | 新增分面标准化处理 | | |

| 452 | +- ✅ 分面结果仅在请求时计算 | |
| 453 | +- ✅ 过滤器逻辑简化，无冗余判断 | |
| 454 | +- ✅ 移除了硬编码的字符串匹配 | |
| 455 | + | |
| 456 | +--- | |
| 457 | + | |
| 458 | +## 关键改进点 | |
| 459 | + | |
| 460 | +### 1. 从硬编码到通用化 | |
| 461 | + | |
| 462 | +**之前**：只支持特定的价格范围 | |
| 463 | +```python | |
| 464 | +if price_range == '0-50': | |
| 465 | + price_ranges.append({"lt": 50}) | |
| 466 | +elif price_range == '50-100': | |
| 467 | + price_ranges.append({"gte": 50, "lt": 100}) | |
| 468 | +# ... | |
| 469 | +``` | |
| 470 | + | |
| 471 | +**现在**：支持任意数值字段和范围 | |
| 472 | +```python | |
| 473 | +for field, range_spec in range_filters.items(): | |
| 474 | + range_conditions = {} | |
| 475 | + for op in ['gte', 'gt', 'lte', 'lt']: | |
| 476 | + if op in range_spec: | |
| 477 | + range_conditions[op] = range_spec[op] | |
| 478 | +``` | |
| 479 | + | |
| 480 | +### 2. 从暴露 ES DSL 到简化接口 | |
| 481 | + | |
| 482 | +**之前**：前端需要了解 ES 语法 | |
| 483 | +```javascript | |
| 484 | +const aggregations = { | |
| 485 | + "category_stats": { | |
| 486 | + "terms": { | |
| 487 | + "field": "categoryName_keyword", | |
| 488 | + "size": 15 | |
| 489 | + } | |
| 490 | + } | |
| 491 | +}; | |
| 492 | +``` | |
| 493 | + | |
| 494 | +**现在**：简化的配置 | |
| 495 | +```javascript | |
| 496 | +const facets = [ | |
| 497 | + {field: "categoryName_keyword", size: 15} | |
| 498 | +]; | |
| 499 | +``` | |
| 500 | + | |
| 501 | +### 3. 从 ES 原始格式到标准化响应 | |
| 502 | + | |
| 503 | +**之前**：需要理解 ES 响应结构 | |
| 504 | +```javascript | |
| 505 | +data.aggregations.category_stats.buckets.forEach(bucket => { | |
| 506 | + console.log(bucket.key, bucket.doc_count); | |
| 507 | +}); | |
| 508 | +``` | |
| 509 | + | |
| 510 | +**现在**：统一的标准化格式 | |
| 511 | +```javascript | |
| 512 | +data.facets.forEach(facet => { | |
| 513 | + facet.values.forEach(value => { | |
| 514 | + console.log(value.label, value.count); | |
| 515 | + }); | |
| 516 | +}); | |
| 517 | +``` | |
| 518 | + | |
| 519 | +--- | |
| 520 | + | |
| 521 | +## 后续工作 | |
