+# 相关性检索优化说明
+
+## 概述
+
+本次优化将相关性检索从简单的 `must` 子句中的 `multi_match` 查询，改为使用 `should` 子句的多查询策略，参考了成熟的搜索实现，显著提升了检索效果。
+
+## 主要改进
+
+## 实现方式
+
+本次优化采用精简实现，直接在 `QueryParser` 中集成必要的分析功能，不新增独立模块。
+
+### 1. 查询结构优化
+
+**之前的结构**（效果差）：
+```json
+{
+  "bool": {
+    "must": [
+      {
+        "multi_match": {
+          "query": "戏水动物",
+          "fields": ["title_zh^3.0", "brief_zh^1.5", ...],
+          "minimum_should_match": "67%",
+          "tie_breaker": 0.9,
+          "boost": 1,
+          "_name": "base_query"
+        }
+      }
+    ]
+  }
+}
+```
+
+**优化后的结构**（效果更好）：
+```json
+{
+  "bool": {
+    "should": [
+      {
+        "multi_match": {
+          "_name": "base_query",
+          "fields": ["title_zh^3.0", "brief_zh^1.5", ...],
+          "minimum_should_match": "75%",
+          "operator": "AND",
+          "query": "戏水动物",
+          "tie_breaker": 0.9
+        }
+      },
+      {
+        "multi_match": {
+          "_name": "base_query_trans_en",
+          "boost": 0.4,
+          "fields": ["title_en^3.0", ...],
+          "minimum_should_match": "75%",
+          "operator": "AND",
+          "query": "water sports (e.g. animals playing with water)",
+          "tie_breaker": 0.9
+        }
+      },
+      {
+        "multi_match": {
+          "query": "戏水动物",
+          "fields": ["title_zh^3.0", "brief_zh^1.5", ...],
+          "type": "phrase",
+          "slop": 2,
+          "boost": 1.0,
+          "_name": "phrase_query"
+        }
+      },
+      {
+        "multi_match": {
+          "query": "戏水 动物",
+          "fields": ["title_zh^3.0", "brief_zh^1.5", ...],
+          "operator": "AND",
+          "tie_breaker": 0.9,
+          "boost": 0.1,
+          "_name": "keywords_query"
+        }
+      }
+    ],
+    "minimum_should_match": 1
+  }
+}
+```
+
+### 2. 集成查询分析功能
+
+在 `QueryParser` 中直接集成必要的分析功能：
+
+- **关键词提取**：使用 HanLP 提取查询中的名词（长度>1），用于关键词查询（可选，HanLP 不可用时降级）
+- **查询类型判断**：区分短查询和长查询
+- **Token 计数**：用于判断查询长度
+
+### 3. 多查询策略
+
+#### 3.1 基础查询（base_query）
+- 使用 `operator: "AND"` 确保所有词都必须匹配
+- `minimum_should_match: "75%"` 提高匹配精度
+- 使用 `tie_breaker: 0.9` 进行分数融合
+
+#### 3.2 翻译查询（base_query_trans_zh/en）
+- 当查询语言不是中文/英文时，添加翻译查询
+- 使用较低的 boost（0.4）避免过度影响
+- 支持跨语言检索
+
+#### 3.3 短语查询（phrase_query）
+- 针对短查询（token_count >= 2 且 is_short_query）
+- 使用 `type: "phrase"` 进行精确短语匹配
+- 支持 slop（允许词序调整）
+
+#### 3.4 关键词查询（keywords_query）
+- 使用 HanLP 提取的名词进行查询
+- 仅在关键词长度合理时启用（避免关键词占查询比例过高）
+- 使用较低的 boost（0.1）作为补充
+
+#### 3.5 长查询优化（long_query）
+- 当前已禁用（参考实现中也是 False）
+- 未来可根据需要启用
+
+### 4. 字段映射优化
+
+新增 `_get_match_fields()` 方法，支持：
+- 根据语言动态获取匹配字段
+- 区分全部字段（all_fields）和核心字段（core_fields）
+- 核心字段用于短语查询和关键词查询，提高精度
+
+## 实现细节
+
+### 文件修改清单
+
+1. **修改文件**：
+   - `query/query_parser.py` - 添加关键词提取、查询类型判断等功能（HanLP 可选）
+   - `search/es_query_builder.py` - 实现 should 子句的多查询策略
+   - `search/searcher.py` - 传递 parsed_query 给查询构建器
+
+### 关键参数说明
+
+- **minimum_should_match**: 从 "67%" 提升到 "75%"，提高匹配精度
+- **operator**: 从默认改为 "AND"，确保所有词都匹配
+- **tie_breaker**: 保持 0.9，用于分数融合
+- **boost 值**：
+  - base_query: 1.0（默认）
+  - translation queries: 0.4
+  - phrase_query: 1.0
+  - keywords_query: 0.1
+
+### 依赖要求
+
+- **HanLP**（可选）：如果安装了 `hanlp` 包，会自动启用关键词提取功能
+  ```bash
+  pip install hanlp
+  ```
+  
+  如果未安装，系统会自动降级到简单分析（基于空格分词），不影响基本功能。
+
+- **HanLP 模型**：首次运行时会自动下载
+  - Tokenizer: `CTB9_TOK_ELECTRA_BASE_CRF`
+  - POS Tagger: `CTB9_POS_ELECTRA_SMALL`
+
+### 配置说明
+
+- **忽略关键词**：在 `_extract_keywords()` 方法中配置
+  - 默认忽略：`['玩具']`
+
+## 使用示例
+
+### 基本使用
+
+查询会自动使用优化后的策略，无需额外配置：
+
+```python
+# 在 searcher.py 中，查询会自动使用优化策略
+result = searcher.search(
+    query="戏水动物",
+    tenant_id="162",
+    size=10
+)
+```
+
+### 查看分析结果
+
+可以直接从 `parsed_query` 查看分析结果：
+
+```python
+parsed_query = query_parser.parse("戏水动物")
+print(f"关键词: {parsed_query.keywords}")
+print(f"Token数: {parsed_query.token_count}")
+print(f"短查询: {parsed_query.is_short_query}")
+print(f"长查询: {parsed_query.is_long_query}")
+```
+
+## 性能考虑
+
+1. **HanLP 初始化**：采用懒加载，首次使用时才初始化
+2. **错误处理**：HanLP 初始化失败或未安装时，系统会降级到简单分析（基于空格分词），不影响服务
+3. **代码精简**：所有功能直接集成在 `QueryParser` 中，无额外模块依赖
+
+## 后续优化方向
+
+1. **长查询优化**：可以启用长查询的特殊处理
+2. **意图识别**：完善意图词典，提供更精准的意图识别
+3. **参数调优**：根据实际效果调整 boost 值和 minimum_should_match
+4. **A/B 测试**：对比优化前后的检索效果
+
+## 注意事项
+
+1. **HanLP 依赖**：HanLP 是可选的，如果未安装或初始化失败，系统会自动降级到简单分析，不会影响基本功能
+2. **性能影响**：HanLP 分析会增加一定的处理时间，但采用懒加载机制
+3. **字段匹配**：确保 ES 索引中存在对应的中英文字段
+4. **代码精简**：所有功能都集成在现有模块中，保持代码结构简洁
