+| `days_since_last_update` | int | 距上次更新天数 |
+
+**注意**: 不同客户可能有不同的字段配置。
+

+
+## 性能优化建议
+
+### 1. 分页
+
+使用 `size` 和 `from` 参数进行分页:
+
+```json
+{
+ "query": "玩具",
+ "size": 20,
+ "from": 0 // 第1页
+}
+
+{
+ "query": "玩具",
+ "size": 20,
+ "from": 20 // 第2页
+}
+```
+
+**建议**:
+- 单页结果数不超过 100
+- 深度分页(from > 10000)性能较差,建议使用 `search_after`(未来版本支持)
+
+### 2. 字段选择
+
+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。
+
+### 3. 缓存
+
+系统自动缓存:
+- 查询向量(避免重复计算)
+- 翻译结果
+- 常见查询结果(未来版本)
+
+### 4. 批量查询
+
+如需批量查询,建议:
+- 使用异步并发请求
+- 控制并发数(建议 ≤ 10)
+- 添加请求间隔(避免限流)
+
+---
+
+## 限流规则
+
+| 端点 | 限制 |
+|------|------|
+| `/search/` | 无限制(生产环境建议配置) |
+| `/search/suggestions` | 60次/分钟 |
+| `/search/instant` | 120次/分钟 |
+| `/admin/*` | 60次/分钟 |
+
+---
+
+## 常见问题
+
+### Q1: 如何判断一个字段应该用哪种过滤器?
+
+**A**:
+- **精确匹配过滤器** (`filters`): 用于 KEYWORD 类型字段(如类目、品牌、标签等)
+- **范围过滤器** (`range_filters`): 用于数值类型字段(如价格、库存、时间等)
+
+### Q2: 可以同时使用多个过滤器吗?
+
+**A**: 可以。多个过滤器之间是 AND 关系(必须同时满足)。
+
+```json
+{
+ "filters": {
+ "categoryName_keyword": "玩具",
+ "brandName_keyword": "乐高"
+ },
+ "range_filters": {
+ "price": {"gte": 50, "lte": 200}
+ }
+}
+```
+结果:类目是"玩具" **并且** 品牌是"乐高" **并且** 价格在50-200之间。
+
+### Q3: 如何实现"价格小于50或大于200"的过滤?
+
+**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。
+
+### Q4: 分面搜索返回的 selected 字段是什么意思?
+
+**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。
+
+### Q5: 如何使用自定义排序?
+
+**A**: 使用 `sort_by` 和 `sort_order` 参数:
+
+```json
+{
+ "query": "玩具",
+ "sort_by": "price",
+ "sort_order": "asc" // 价格从低到高
+}
+```
+
+常用排序字段:
+- `price`: 价格
+- `create_time`: 创建时间
+- `days_since_last_update`: 更新时间
+
+### Q6: 如何启用调试模式?
+
+**A**: 设置 `debug: true`,响应中会包含 `debug_info` 字段,包含:
+- 查询分析过程
+- ES 查询 DSL
+- ES 响应详情
+- 各阶段耗时
+
+---
+
+## 版本历史
+
+### v3.0 (2024-11-12)
+
+**重大更新**:
+- ✅ 移除硬编码的 `price_ranges` 逻辑
+- ✅ 新增 `range_filters` 参数,支持任意数值字段的范围过滤
+- ✅ 新增 `facets` 参数,替代 `aggregations`,提供简化接口
+- ✅ 标准化分面搜索响应格式
+- ✅ 新增 `/search/suggestions` 端点(框架)
+- ✅ 新增 `/search/instant` 端点(框架)
+- ❌ **移除** `aggregations` 参数(不向后兼容)
+
+**迁移指南**:
+
+旧接口:
+```json
+{
+ "filters": {
+ "price_ranges": ["0-50", "50-100"]
+ },
+ "aggregations": {
+ "category_stats": {"terms": {"field": "categoryName_keyword", "size": 15}}
+ }
+}
+```
+
+新接口:
+```json
+{
+ "range_filters": {
+ "price": {"gte": 50, "lte": 100}
+ },
+ "facets": [
+ {"field": "categoryName_keyword", "size": 15}
+ ]
+}
+```

+ }
+ },
+ "sort_by": "create_time",
+ "sort_order": "desc",
+ "size": 20
+ }'
+```
+
+---
+
+## 错误处理
+
+### 示例 1:参数错误
+
+```bash
+# 错误:range_filters 缺少操作符
+curl -X POST "http://localhost:6002/search/" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "query": "玩具",
+ "range_filters": {
+ "price": {}
+ }
+ }'
+```
+
+**响应**:
+```json
+{
+ "error": "Validation error",
+ "detail": "至少需要指定一个范围边界(gte, gt, lte, lt)",
+ "timestamp": 1699800000
+}
+```
+
+### 示例 2:空查询
+
+```bash
+# 错误:query 为空
+curl -X POST "http://localhost:6002/search/" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "query": ""
+ }'
+```
+
+**响应**:
+```json
+{
+ "error": "Validation error",
+ "detail": "query field required",
+ "timestamp": 1699800000
+}
+```
+
+---
+
+## 性能优化建议
+
+### 1. 合理使用分面
+
+```bash
+# ❌ 不推荐:请求太多分面
+{
+ "facets": [
+ {"field": "field1", "size": 100},
+ {"field": "field2", "size": 100},
+ {"field": "field3", "size": 100},
+ // ... 10+ facets
+ ]
+}
+
+# ✅ 推荐:只请求必要的分面
+{
+ "facets": [
+ {"field": "categoryName_keyword", "size": 15},
+ {"field": "brandName_keyword", "size": 15}
+ ]
+}
+```
+
+### 2. 控制返回数量
+
+```bash
+# ❌ 不推荐:一次返回太多
+{
+ "size": 100
+}
+
+# ✅ 推荐:分页查询
+{
+ "size": 20,
+ "from": 0
+}
+```
+
+### 3. 使用适当的过滤器
+
+```bash
+# ✅ 推荐:先过滤后搜索
+{
+ "query": "玩具",
+ "filters": {
+ "categoryName_keyword": "玩具"
+ }
+}
+```
+
+---
+
+## 高级技巧
+
+### 技巧 1:获取所有类目
+
+```bash
+# 使用通配符查询 + 分面
+curl -X POST "http://localhost:6002/search/" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "query": "*",
+ "size": 0,
+ "facets": [
+ {"field": "categoryName_keyword", "size": 100}
+ ]
+ }'
+```
+
+### 技巧 2:价格分布统计
+
+```bash
+curl -X POST "http://localhost:6002/search/" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "query": "玩具",
+ "size": 0,
+ "facets": [
+ {
+ "field": "price",
+ "type": "range",
+ "ranges": [
+ {"key": "0-50", "to": 50},
+ {"key": "50-100", "from": 50, "to": 100},
+ {"key": "100-200", "from": 100, "to": 200},
+ {"key": "200-500", "from": 200, "to": 500},
+ {"key": "500+", "from": 500}
+ ]
+ }
+ ]
+ }'
+```
+
+### 技巧 3:组合多种查询类型
+
+```bash
+# 布尔表达式 + 过滤器 + 分面 + 排序
+curl -X POST "http://localhost:6002/search/" \
+ -H "Content-Type: application/json" \
+ -d '{
+ "query": "(玩具 OR 游戏) AND 儿童 ANDNOT 电子",
+ "filters": {
+ "categoryName_keyword": ["玩具", "益智玩具"]
+ },
+ "range_filters": {
+ "price": {"gte": 20, "lte": 100},
+ "days_since_last_update": {"lte": 30}
+ },
+ "facets": [
+ {"field": "brandName_keyword", "size": 20}
+ ],
+ "sort_by": "price",
+ "sort_order": "asc",
+ "size": 20
+ }'
+```
+
+---
+
+## 测试数据

+
+## v3.0 - API 接口重构 (2024-11-12)
+
+### 重大更新
+
+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。
+
+#### ❌ 破坏性变更(不向后兼容)
+
+1. **移除硬编码的 price_ranges 参数**
+ - 旧方式:`filters: {"price_ranges": ["0-50", "50-100"]}`
+ - 新方式:`range_filters: {"price": {"gte": 50, "lte": 100}}`
+
+2. **移除 aggregations 参数**
+ - 旧方式:`aggregations: {"category_stats": {"terms": {...}}}`(ES DSL)
+ - 新方式:`facets: [{"field": "categoryName_keyword", "size": 15}]`(简化配置)
+
+3. **响应格式变更**
+ - 旧方式:`response.aggregations`(ES 原始格式)
+ - 新方式:`response.facets`(标准化格式)
+
+#### ✅ 新增功能
+
+1. **结构化过滤参数**
+ - 新增 `range_filters` 参数:支持任意数值字段的范围过滤
+ - 支持 `gte`, `gt`, `lte`, `lt` 操作符
+ - 示例:
+ ```json
+ {
+ "range_filters": {
+ "price": {"gte": 50, "lte": 200},
+ "days_since_last_update": {"lte": 30}
+ }
+ }
+ ```
+
+2. **简化的分面配置**
+ - 新增 `facets` 参数:替代复杂的 ES DSL
+ - 支持简单模式(字符串数组)和高级模式(配置对象)
+ - 示例:
+ ```json
+ {
+ "facets": [
+ "categoryName_keyword", // 简单模式
+ {"field": "brandName_keyword", "size": 15} // 高级模式
+ ]
+ }
+ ```
+
+3. **标准化分面响应**
+ - 统一的分面结果格式
+ - 包含 `field`, `label`, `type`, `values`
+ - `values` 包含 `value`, `label`, `count`, `selected`
+ - 示例:
+ ```json
+ {
+ "facets": [
+ {
+ "field": "categoryName_keyword",
+ "label": "商品类目",
+ "type": "terms",
+ "values": [
+ {"value": "玩具", "label": "玩具", "count": 85, "selected": false}
+ ]
+ }
+ ]
+ }
+ ```
+
+4. **新增搜索建议端点**(框架)
+ - `GET /search/suggestions`: 自动补全
+ - `GET /search/instant`: 即时搜索
+ - 注:暂未实现,仅返回框架响应
+
+#### 🔧 代码改进
+
+1. **后端模型层** (`api/models.py`)
+ - 新增 `RangeFilter` 模型
+ - 新增 `FacetConfig` 模型
+ - 新增 `FacetValue` 和 `FacetResult` 模型
+ - 更新 `SearchRequest` 和 `SearchResponse`
+
+2. **查询构建器** (`search/es_query_builder.py`)
+ - **完全移除** 硬编码的 `price_ranges` 逻辑(第 205-233 行)
+ - 重构 `_build_filters` 方法,支持 `range_filters`
+ - **删除** `add_dynamic_aggregations` 方法
+ - 新增 `build_facets` 方法
+
+3. **搜索执行层** (`search/searcher.py`)
+ - 更新 `search()` 方法签名
+ - 新增 `_standardize_facets()` 方法
+ - 新增 `_get_field_label()` 方法
+ - 更新 `SearchResult` 类
+
+4. **API 路由层** (`api/routes/search.py`)
+ - 更新所有搜索端点
+ - 新增 `/search/suggestions` 端点
+ - 新增 `/search/instant` 端点
+
+5. **前端代码** (`frontend/static/js/app.js`)
+ - 更新状态管理,添加 `rangeFilters`
+ - 完全重写 `displayAggregations` 为 `displayFacets`
+ - 更新过滤器处理逻辑
+ - 删除所有硬编码的 `price_ranges`
+
+#### 📚 文档更新
+
+- 新增 `API_DOCUMENTATION.md`:完整的 API 接口文档
+- 更新 `README.md`:添加 v3.0 新功能说明
+- 更新 `USER_GUIDE.md`:更新 API 使用示例
+
+#### 🎯 改进要点
+
+**从特定实现到通用 SaaS**:
+- ❌ 移除:硬编码的价格范围值
+- ❌ 移除:暴露 ES DSL 的聚合接口
+- ❌ 移除:不统一的响应格式
+- ✅ 新增:通用的范围过滤器
+- ✅ 新增:简化的分面配置
+- ✅ 新增:标准化的响应格式
+
+#### 📋 迁移指南
+
+**旧接口** → **新接口**
+
+1. **过滤器迁移**:
+ ```json
+ // 旧
+ {"filters": {"price_ranges": ["50-100"]}}
+
+ // 新
+ {"range_filters": {"price": {"gte": 50, "lte": 100}}}
+ ```
+
+2. **聚合迁移**:
+ ```json
+ // 旧
+ {
+ "aggregations": {
+ "category_stats": {
+ "terms": {"field": "categoryName_keyword", "size": 15}
+ }
+ }
+ }
+
+ // 新
+ {
+ "facets": [
+ {"field": "categoryName_keyword", "size": 15}
+ ]
+ }
+ ```
+
+3. **响应解析迁移**:
+ ```javascript
+ // 旧
+ data.aggregations.category_stats.buckets.forEach(bucket => {
+ console.log(bucket.key, bucket.doc_count);
+ });
+
+ // 新
+ data.facets.forEach(facet => {
+ facet.values.forEach(value => {
+ console.log(value.value, value.count);
+ });
+ });
+ ```

+# Facets 类型优化总结
+
+## 问题描述
+
+ES查询中的 aggs(聚合/分面)返回为空,原因是数据类型不一致:
+
+- `SearchResponse.facets` 定义为 `List[FacetResult]`(Pydantic 模型)
+- `Searcher._standardize_facets()` 返回 `List[Dict[str, Any]]`(字典列表)
+- 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
+
+## 解决方案
+
+**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。
+
+### 修改内容
+
+#### 1. `/home/tw/SearchEngine/search/searcher.py`
+
+**导入 Pydantic 模型**:
+```python
+from api.models import FacetResult, FacetValue
+```
+
+**修改 `SearchResult` 类**:
+- `facets` 参数类型从 `Optional[List[Dict[str, Any]]]` 改为 `Optional[List[FacetResult]]`
+- `to_dict()` 方法中添加模型序列化:
+ ```python
+ "facets": [f.model_dump() for f in self.facets] if self.facets else None
+ ```
+
+**修改 `_standardize_facets()` 方法**:
+- 返回类型从 `Optional[List[Dict[str, Any]]]` 改为 `Optional[List[FacetResult]]`
+- 直接构建 `FacetValue` 对象:
+ ```python
+ facet_values.append(FacetValue(
+ value=value,
+ label=str(value),
+ count=count,
+ selected=value in selected_values
+ ))
+ ```
+- 直接构建 `FacetResult` 对象:
+ ```python
+ facet_result = FacetResult(
+ field=field,
+ label=self._get_field_label(field),
+ type=facet_type,
+ values=facet_values
+ )
+ ```
+
+## 优势
+
+### 1. **类型安全**
+- 静态类型检查工具(如 mypy)可以捕获类型错误
+- IDE 提供更好的代码补全和类型提示
+
+### 2. **早期验证**
+- 数据问题在构建时立即发现,而不是等到 API 响应时
+- 如果数据不符合模型定义,会在 `_standardize_facets()` 中抛出明确的错误
+
+### 3. **避免隐式转换**
+- 不依赖 Pydantic 的运行时转换逻辑
+- 减少因 Pydantic 版本差异导致的行为变化
+
+### 4. **代码清晰**
+- 意图明确:代码明确表示返回的是 Pydantic 模型
+- 易于维护:后续开发者能清楚理解数据流
+
+### 5. **性能优化**
+- 避免 Pydantic 在 API 层的重复验证
+- 减少一次数据转换过程
+
+## 兼容性
+
+此修改**完全向后兼容**:
+
+1. **API 接口不变**:`SearchResponse` 模型定义保持不变
+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
+3. **数据结构不变**:FacetResult 和 FacetValue 的字段定义没有改变
+
+## 测试建议
+
+### 单元测试
+```python
+def test_standardize_facets_returns_models():
+ """测试 _standardize_facets 返回 FacetResult 对象"""
+ searcher = create_test_searcher()
+
+ es_aggs = {
+ "categoryName_keyword_facet": {
+ "buckets": [
+ {"key": "玩具", "doc_count": 100},
+ {"key": "益智玩具", "doc_count": 50}
+ ]
+ }
+ }
+
+ facet_configs = ["categoryName_keyword"]
+
+ result = searcher._standardize_facets(es_aggs, facet_configs)
+
+ assert isinstance(result, list)
+ assert isinstance(result[0], FacetResult)
+ assert isinstance(result[0].values[0], FacetValue)
+```
+
+### 集成测试
+```python
+def test_search_with_facets_returns_correct_type():
+ """测试搜索返回正确的 facets 类型"""
+ result = searcher.search(
+ query="玩具",
+ facets=["categoryName_keyword", "brandName_keyword"]
+ )
+
+ assert result.facets is not None
+ assert isinstance(result.facets[0], FacetResult)
+
+ # 测试序列化
+ result_dict = result.to_dict()
+ assert isinstance(result_dict["facets"], list)
+ assert isinstance(result_dict["facets"][0], dict)
+```
+
+### API 测试
+```python
+def test_api_facets_response():
+ """测试 API 返回的 facets 格式"""
+ response = client.post("/search/", json={
+ "query": "玩具",
+ "facets": ["categoryName_keyword"]
+ })
+
+ assert response.status_code == 200
+ data = response.json()
+
+ assert "facets" in data
+ assert isinstance(data["facets"], list)
+
+ if data["facets"]:
+ facet = data["facets"][0]
+ assert "field" in facet
+ assert "label" in facet
+ assert "type" in facet
+ assert "values" in facet
+
+ if facet["values"]:
+ value = facet["values"][0]
+ assert "value" in value
+ assert "label" in value
+ assert "count" in value
+ assert "selected" in value
+```
+
+## 最佳实践总结
+
+这次修改体现了以下软件工程最佳实践:
+
+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
+2. **早期验证**:在数据流的源头进行验证,而不是末端
+3. **单一数据表示**:避免同一数据在代码中有多种表示形式
+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)
+5. **关注点分离**:Searcher 负责业务逻辑,Pydantic 负责数据验证
+
+## 后续改进建议
+
+1. **添加类型检查**:在 CI/CD 中加入 mypy 静态类型检查
+2. **更新测试**:确保所有测试使用新的 `facets` 字段(而不是旧的 `aggregations`)
+3. **性能监控**:对比修改前后的性能差异(预期会有轻微提升)
+4. **文档更新**:更新 API 文档,强调 facets 的类型安全特性

+# API v3.0 迁移指南
+
+本文档帮助你从旧版 API 迁移到 v3.0。
+
+---
+
+## 重要变更概述
+
+v3.0 是一个**不向后兼容**的版本,主要变更包括:
+
+1. ❌ **移除** 硬编码的 `price_ranges` 参数
+2. ❌ **移除** `aggregations` 参数(ES DSL)
+3. ✅ **新增** `range_filters` 参数
+4. ✅ **新增** `facets` 参数(简化接口)
+5. ✅ **新增** 标准化的分面响应格式
+
+---
+
+## 迁移步骤
+
+### 第一步:更新过滤器参数
+
+#### 旧代码(v2.x)
+
+```json
+{
+ "query": "玩具",
+ "filters": {
+ "price_ranges": ["0-50", "50-100"]
+ }
+}
+```
+
+#### 新代码(v3.0)
+
+```json
+{
+ "query": "玩具",
+ "range_filters": {
+ "price": {
+ "gte": 50,
+ "lte": 100
+ }
+ }
+}
+```
+
+#### 迁移对照表
+
+| 旧格式 | 新格式 |
+|--------|--------|
+| `"price_ranges": ["0-50"]` | `"price": {"lt": 50}` |
+| `"price_ranges": ["50-100"]` | `"price": {"gte": 50, "lt": 100}` |
+| `"price_ranges": ["100-200"]` | `"price": {"gte": 100, "lt": 200}` |
+| `"price_ranges": ["200+"]` | `"price": {"gte": 200}` |
+
+### 第二步:更新聚合参数
+
+#### 旧代码(v2.x)
+
+```json
+{
+ "query": "玩具",
+ "aggregations": {
+ "category_stats": {
+ "terms": {
+ "field": "categoryName_keyword",
+ "size": 15
+ }
+ },
+ "brand_stats": {
+ "terms": {
+ "field": "brandName_keyword",
+ "size": 15
+ }
+ }
+ }
+}
+```
+
+#### 新代码(v3.0)- 简单模式
+
+```json
+{
+ "query": "玩具",
+ "facets": ["categoryName_keyword", "brandName_keyword"]
+}
+```
+
+#### 新代码(v3.0)- 高级模式
+
+```json
+{
+ "query": "玩具",
+ "facets": [
+ {
+ "field": "categoryName_keyword",
+ "size": 15,
+ "type": "terms"
+ },
+ {
+ "field": "brandName_keyword",
+ "size": 15,
+ "type": "terms"
+ }
+ ]
+}
+```
+
+### 第三步:更新响应解析
+
+#### 旧代码(v2.x)
+
+```javascript
+// JavaScript
+const data = await response.json();
+
+// 解析聚合结果(ES 原始格式)
+if (data.aggregations && data.aggregations.category_stats) {
+ data.aggregations.category_stats.buckets.forEach(bucket => {
+ console.log(bucket.key, bucket.doc_count);
+ });
+}
+```
+
+```python
+# Python
+data = response.json()
+
+# 解析聚合结果(ES 原始格式)
+if 'aggregations' in data and 'category_stats' in data['aggregations']:
+ for bucket in data['aggregations']['category_stats']['buckets']:
+ print(bucket['key'], bucket['doc_count'])
+```
+
+#### 新代码(v3.0)
+
+```javascript
+// JavaScript
+const data = await response.json();
+
+// 解析分面结果(标准化格式)
+if (data.facets) {
+ data.facets.forEach(facet => {
+ console.log(`${facet.label} (${facet.type}):`);
+ facet.values.forEach(value => {
+ console.log(` ${value.label}: ${value.count}`);
+ });
+ });
+}
+```
+
+```python
+# Python
+data = response.json()
+
+# 解析分面结果(标准化格式)
+if 'facets' in data:
+ for facet in data['facets']:
+ print(f"{facet['label']} ({facet['type']}):")
+ for value in facet['values']:
+ print(f" {value['label']}: {value['count']}")
+```
+
+---
+
+## 完整迁移示例
+
+### 示例 1:带价格过滤的搜索
+
+#### 旧代码
+
+```python
+import requests
+
+response = requests.post('http://localhost:6002/search/', json={
+ "query": "玩具",
+ "size": 20,
+ "filters": {
+ "categoryName_keyword": "玩具",
+ "price_ranges": ["50-100", "100-200"]
+ },
+ "aggregations": {
+ "brand_stats": {
+ "terms": {
+ "field": "brandName_keyword",
+ "size": 15
+ }
+ }
+ }
+})
+
+data = response.json()
+
+# 解析聚合
+for bucket in data['aggregations']['brand_stats']['buckets']:
+ print(f"{bucket['key']}: {bucket['doc_count']}")
+```
+
+#### 新代码
+
+```python
+import requests
+
+response = requests.post('http://localhost:6002/search/', json={
+ "query": "玩具",
+ "size": 20,
+ "filters": {
+ "categoryName_keyword": "玩具"
+ },
+ "range_filters": {
+ "price": {
+ "gte": 50,
+ "lte": 200
+ }
+ },
+ "facets": [
+ {"field": "brandName_keyword", "size": 15}
+ ]
+})
+
+data = response.json()
+
+# 解析分面
+for facet in data['facets']:
+ if facet['field'] == 'brandName_keyword':
+ for value in facet['values']:
+ print(f"{value['label']}: {value['count']}")
+```
+
+### 示例 2:前端 JavaScript 迁移
+
+#### 旧代码
+
+```javascript
+// 构建请求
+const requestBody = {
+ query: "玩具",
+ filters: {
+ price_ranges: ["50-100"]
+ },
+ aggregations: {
+ category_stats: {
+ terms: {
+ field: "categoryName_keyword",
+ size: 15
+ }
+ }
+ }
+};
+
+// 发送请求
+const response = await fetch('/search/', {
+ method: 'POST',
+ headers: {'Content-Type': 'application/json'},
+ body: JSON.stringify(requestBody)
+});
+
+const data = await response.json();
+
+// 显示聚合结果
+const buckets = data.aggregations.category_stats.buckets;
+buckets.forEach(bucket => {
+ console.log(`${bucket.key}: ${bucket.doc_count}`);
+});
+```
+
+#### 新代码
+
+```javascript
+// 构建请求
+const requestBody = {
+ query: "玩具",
+ range_filters: {
+ price: {
+ gte: 50,
+ lte: 100
+ }
+ },
+ facets: [
+ {field: "categoryName_keyword", size: 15}
+ ]
+};
+
+// 发送请求
+const response = await fetch('/search/', {
+ method: 'POST',
+ headers: {'Content-Type': 'application/json'},
+ body: JSON.stringify(requestBody)
+});
+
+const data = await response.json();
+
+// 显示分面结果
+data.facets.forEach(facet => {
+ console.log(`${facet.label}:`);
+ facet.values.forEach(value => {
+ console.log(` ${value.label}: ${value.count}`);
+ });
+});
+```
+
+---
+
+## 字段映射对照
+
+### 请求字段
+
+| v2.x | v3.0 | 说明 |
+|------|------|------|
+| `filters.price_ranges` | `range_filters.price` | 价格范围过滤 |
+| `aggregations` | `facets` | 分面配置 |
+| - | `range_filters.*` | 任意数值字段范围过滤 |
+
+### 响应字段
+
+| v2.x | v3.0 | 说明 |
+|------|------|------|
+| `aggregations` | `facets` | 分面结果 |
+| `aggregations.*.buckets[].key` | `facets[].values[].value` | 分面值 |
+| `aggregations.*.buckets[].doc_count` | `facets[].values[].count` | 文档数量 |
+| - | `facets[].values[].label` | 显示标签 |
+| - | `facets[].values[].selected` | 是否选中 |
+| - | `facets[].label` | 分面名称 |
+| - | `facets[].type` | 分面类型 |
+
+---
+
+## 常见问题
+
+### Q1: 我的代码使用了 `price_ranges`,如何迁移?
+
+**A**: 使用 `range_filters` 替代:
+
+```python
+# 旧
+filters = {"price_ranges": ["50-100"]}
+
+# 新
+range_filters = {"price": {"gte": 50, "lte": 100}}
+```
+
+### Q2: 我使用了 ES 聚合语法,如何迁移?
+
+**A**: 使用简化的 `facets` 配置:
+
+```python
+# 旧
+aggregations = {
+ "my_agg": {
+ "terms": {
+ "field": "categoryName_keyword",
+ "size": 15
+ }
+ }
+}
+
+# 新(简单模式)
+facets = ["categoryName_keyword"]
+
+# 新(高级模式)
+facets = [
+ {"field": "categoryName_keyword", "size": 15}
+]
+```
+
+### Q3: 响应中的 `aggregations` 字段去哪了?
+
+**A**: 已改名为 `facets`,并且格式标准化了:
+
+```python
+# 旧
+for bucket in data['aggregations']['category_stats']['buckets']:
+ print(bucket['key'], bucket['doc_count'])
+
+# 新
+for facet in data['facets']:
+ for value in facet['values']:
+ print(value['value'], value['count'])
+```
+
+### Q4: 如何实现多个不连续的价格范围?
+
+**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:
+
+```python
+# 方案1:分两次查询
+result1 = search(query="玩具", range_filters={"price": {"lt": 50}})
+result2 = search(query="玩具", range_filters={"price": {"gte": 200}})
+
+# 方案2:使用范围分面统计(不过滤,只统计)
+facets = [{
+ "field": "price",
+ "type": "range",
+ "ranges": [
+ {"key": "低价", "to": 50},
+ {"key": "高价", "from": 200}
+ ]
+}]
+```
+
+### Q5: 我需要继续使用旧接口,怎么办?
+
+**A**: v3.0 不提供向后兼容。建议:
+1. 尽快迁移到新接口
+2. 如果暂时无法迁移,请继续使用 v2.x 版本
+3. 参考本文档快速完成迁移(通常只需要 1-2 小时)

+{
+ "range_filters": {
+ "price": {"gte": 50, "lte": 200},
+ "days_since_last_update": {"lte": 30}
+ }
+}
+```
+
+**优势**:
+- 支持任意数值字段的范围过滤
+- 清晰的参数分离
+- 类型明确,易于验证
+
+### 2. 简化的分面配置 ✅
+
+**简单模式**:
+```json
+{
+ "facets": ["categoryName_keyword", "brandName_keyword"]
+}
+```
+
+**高级模式**:
+```json
+{
+ "facets": [
+ {"field": "categoryName_keyword", "size": 15},
+ {
+ "field": "price",
+ "type": "range",
+ "ranges": [
+ {"key": "0-50", "to": 50},
+ {"key": "50-100", "from": 50, "to": 100}
+ ]
+ }
+ ]
+}
+```
+
+**优势**:
+- 不暴露 ES DSL
+- 易于理解和使用
+- 支持简单和高级两种模式
+
+### 3. 标准化分面响应 ✅
+
+**响应格式**:
+```json
+{
+ "facets": [
+ {
+ "field": "categoryName_keyword",
+ "label": "商品类目",
+ "type": "terms",
+ "values": [
+ {
+ "value": "玩具",
+ "label": "玩具",
+ "count": 85,
+ "selected": false
+ }
+ ]
+ }
+ ]
+}
+```
+
+**优势**:
+- 统一的响应格式
+- 包含显示标签
+- 包含选中状态
+- 前端解析简单
+
+### 4. 搜索建议框架 ✅
+
+**新端点**:
+- `GET /search/suggestions` - 自动补全
+- `GET /search/instant` - 即时搜索
+
+**状态**: 框架已实现,具体功能待实现
+
+---
+
+## 破坏性变更
+
+### ❌ 已移除
+
+1. **硬编码的 price_ranges**
+ - 位置:`search/es_query_builder.py` 第 205-233 行
+ - 原因:缺乏通用性,只支持特定价格范围
+
+2. **aggregations 参数**
+ - 位置:`api/models.py` 第 17 行
+ - 原因:直接暴露 ES DSL,不符合 SaaS 易用性原则
+
+3. **add_dynamic_aggregations 方法**
+ - 位置:`search/es_query_builder.py` 第 298-319 行
+ - 原因:功能由 build_facets 替代
+
+4. **SearchResult.aggregations 属性**
+ - 位置:`search/searcher.py`
+ - 原因:改为标准化的 facets 属性
+
+---
+
+## 新增的 API 端点
+
+| 端点 | 方法 | 状态 | 描述 |
+|------|------|------|------|
+| `/search/suggestions` | GET | 框架 | 搜索建议(自动补全) |

+```
+
+### 功能测试
+
+运行 `test_new_api.py` 测试所有新功能:
+```bash
+python3 test_new_api.py
+```
+
+**测试覆盖**:
+- ✅ 简单搜索
+- ✅ 范围过滤器
+- ✅ 组合过滤器
+- ✅ 分面搜索(简单模式)
+- ✅ 分面搜索(高级模式)
+- ✅ 完整场景
+- ✅ 搜索建议端点
+- ✅ 即时搜索端点
+- ✅ 参数验证
+
+---
+
+## 性能影响
+
+### 预期性能影响
+
+| 指标 | 变化 | 说明 |
+|------|------|------|
+| 查询构建 | +5-10ms | 新增分面标准化处理 |
+| 响应大小 | 略增 | 标准化格式包含更多元数据 |
+| 总体延迟 | <5% | 影响可忽略 |
+
+### 性能优化
+
+- ✅ 分面结果仅在请求时计算
+- ✅ 过滤器逻辑简化,无冗余判断
+- ✅ 移除了硬编码的字符串匹配
+
+---
+
+## 关键改进点
+
+### 1. 从硬编码到通用化
+
+**之前**:只支持特定的价格范围
+```python
+if price_range == '0-50':
+ price_ranges.append({"lt": 50})
+elif price_range == '50-100':
+ price_ranges.append({"gte": 50, "lt": 100})
+# ...
+```
+
+**现在**:支持任意数值字段和范围
+```python
+for field, range_spec in range_filters.items():
+ range_conditions = {}
+ for op in ['gte', 'gt', 'lte', 'lt']:
+ if op in range_spec:
+ range_conditions[op] = range_spec[op]
+```
+
+### 2. 从暴露 ES DSL 到简化接口
+
+**之前**:前端需要了解 ES 语法
+```javascript
+const aggregations = {
+ "category_stats": {
+ "terms": {
+ "field": "categoryName_keyword",
+ "size": 15
+ }
+ }
+};
+```
+
+**现在**:简化的配置
+```javascript
+const facets = [
+ {field: "categoryName_keyword", size: 15}
+];
+```
+
+### 3. 从 ES 原始格式到标准化响应
+
+**之前**:需要理解 ES 响应结构
+```javascript
+data.aggregations.category_stats.buckets.forEach(bucket => {
+ console.log(bucket.key, bucket.doc_count);
+});
+```
+
+**现在**:统一的标准化格式
+```javascript
+data.facets.forEach(facet => {
+ facet.values.forEach(value => {
+ console.log(value.label, value.count);
+ });
+});
+```
+
+---
+
