+# API清理总结报告
+
+## 🎯 清理目标
+
+移除前端API中的内部参数，使复杂功能对用户透明，简化API接口。
+
+## ❌ 清理前的问题
+
+### 暴露的内部参数
+```json
+{
+  "query": "芭比娃娃",
+  "size": 10,
+  "from_": 0,
+  "enable_translation": true,    // ❌ 用户不需要关心
+  "enable_embedding": true,      // ❌ 用户不需要关心
+  "enable_rerank": true,         // ❌ 用户不需要关心
+  "min_score": null
+}
+```
+
+### 前端日志显示
+```
+enable_translation=False, enable_embedding=False, enable_rerank=True
+```
+
+用户需要了解和配置内部功能，违背了系统设计的简洁性原则。
+
+## ✅ 清理方案
+
+### 1. API模型清理
+**文件**: `api/models.py`
+
+**清理前**:
+```python
+class SearchRequest(BaseModel):
+    query: str = Field(...)
+    size: int = Field(10, ge=1, le=100)
+    from_: int = Field(0, ge=0, alias="from")
+    filters: Optional[Dict[str, Any]] = Field(None)
+    enable_translation: bool = Field(True)      # ❌ 移除
+    enable_embedding: bool = Field(True)        # ❌ 移除
+    enable_rerank: bool = Field(True)           # ❌ 移除
+    min_score: Optional[float] = Field(None)
+```
+
+**清理后**:
+```python
+class SearchRequest(BaseModel):
+    query: str = Field(...)
+    size: int = Field(10, ge=1, le=100)
+    from_: int = Field(0, ge=0, alias="from")
+    filters: Optional[Dict[str, Any]] = Field(None)
+    min_score: Optional[float] = Field(None)
+```
+
+### 2. API路由清理
+**文件**: `api/routes/search.py`
+
+**清理前**:
+```python
+result = searcher.search(
+    query=request.query,
+    enable_translation=request.enable_translation,    # ❌ 移除
+    enable_embedding=request.enable_embedding,        # ❌ 移除
+    enable_rerank=request.enable_rerank,             # ❌ 移除
+    # ...
+)
+```
+
+**清理后**:
+```python
+result = searcher.search(
+    query=request.query,
+    # 使用后端配置默认值
+)
+```
+
+### 3. 搜索器参数清理
+**文件**: `search/searcher.py`
+
+**清理前**:
+```python
+def search(
+    self,
+    query: str,
+    enable_translation: Optional[bool] = None,    # ❌ 移除
+    enable_embedding: Optional[bool] = None,        # ❌ 移除
+    enable_rerank: bool = True,                     # ❌ 移除
+    # ...
+):
+```
+
+**清理后**:
+```python
+def search(
+    self,
+    query: str,
+    # 使用配置文件默认值
+    # ...
+):
+    # 始终使用配置默认值
+    enable_translation = self.config.query_config.enable_translation
+    enable_embedding = self.config.query_config.enable_text_embedding
+    enable_rerank = True
+```
+
+## 🧪 清理验证
+
+### ✅ API模型验证
+```python
+# 创建请求不再需要内部参数
+search_request = SearchRequest(
+    query="芭比娃娃",
+    size=10,
+    filters={"categoryName": "玩具"}
+)
+
+# 验证内部参数已移除
+assert not hasattr(search_request, 'enable_translation')
+assert not hasattr(search_request, 'enable_embedding')
+assert not hasattr(search_request, 'enable_rerank')
+```
+
+### ✅ 功能透明性验证
+```python
+# 前端调用简洁明了
+frontend_request = {
+    "query": "芭比娃娃",
+    "size": 10,
+    "filters": {"categoryName": "玩具"}
+}
+
+# 后端自动使用配置默认值
+backend_flags = {
+    "translation_enabled": True,    # 来自配置文件
+    "embedding_enabled": True,      # 来自配置文件
+    "rerank_enabled": True          # 固定启用
+}
+```
+
+### ✅ 日志验证
+**清理前**:
+```
+enable_translation=False, enable_embedding=False, enable_rerank=True
+```
+
+**清理后**:
+```
+enable_translation=True, enable_embedding=True, enable_rerank=True
+```
+
+## 🎊 清理结果
+
+### ✅ 用户友好的API
+```json
+{
+  "query": "芭比娃娃",
+  "size": 10,
+  "from_": 0,
+  "filters": {

+# 错误修复报告：请求上下文和日志系统
+
+## 🐛 问题描述
+
+在集成请求上下文管理器后，系统出现了以下错误：
+
+```
+TypeError: Logger._log() got an unexpected keyword argument 'reqid'
+```
+
+错误发生在搜索请求处理过程中，导致搜索功能完全不可用。
+
+## 🔍 问题分析
+
+根本原因是日志调用的格式不正确。Python 标准库的 `logger.info()`、`logger.debug()` 等方法不接受任意的 `reqid` 和 `uid` 关键字参数，需要通过 `extra` 参数传递。
+
+## 🔧 修复内容
+
+### 1. `utils/logger.py`
+- **问题**: 缺少对自定义参数的处理
+- **修复**: 添加了 `_log_with_context()` 辅助函数来正确处理自定义参数
+- **状态**: ✅ 已修复
+
+### 2. `context/request_context.py`
+- **问题**: 多处日志调用直接使用 `reqid=..., uid=...` 参数
+- **修复**: 所有日志调用改为使用 `extra={'reqid': ..., 'uid': ...}` 格式
+- **影响**: 7处日志调用修复
+- **状态**: ✅ 已修复
+
+### 3. `query/query_parser.py`
+- **问题**: 查询解析中的日志调用格式错误
+- **修复**: 修复了内部日志函数的参数传递格式
+- **影响**: 2处日志调用修复
+- **状态**: ✅ 已修复
+
+### 4. `search/searcher.py`
+- **问题**: 搜索过程中的日志调用格式错误
+- **修复**: 批量替换所有日志调用格式
+- **影响**: 多处日志调用修复
+- **状态**: ✅ 已修复
+
+### 5. `api/routes/search.py`
+- **问题**: API路由中的日志调用格式错误
+- **修复**: 修复日志调用格式
+- **状态**: ✅ 已修复
+
+## ✅ 验证结果
+
+通过 `verification_report.py` 进行了全面测试：
+
+- ✅ 基础模块导入正常
+- ✅ 日志系统正常工作
+- ✅ 请求上下文创建正常
+- ✅ 查询解析功能正常（修复验证）
+- ✅ 中文查询处理正常
+- ✅ 性能摘要生成正常

+# RequestContext 使用指南
+
+## 概述
+
+`RequestContext` 是一个请求粒度的上下文管理器，用于跟踪和管理搜索请求的整个生命周期。它提供了统一的数据存储、性能监控和日志记录功能。
+
+## 核心功能
+
+### 1. 查询分析结果存储
+- 原始查询、规范化查询、重写查询
+- 检测语言和翻译结果
+- 查询向量（embedding）
+- 布尔查询AST
+
+### 2. 各检索阶段中间结果
+- 解析后的查询对象
+- 布尔查询语法树
+- ES查询DSL
+- ES响应数据
+- 处理后的搜索结果
+
+### 3. 性能监控
+- 自动计时各阶段耗时
+- 计算各阶段耗时占比
+- 识别性能瓶颈
+- 详细的性能摘要日志
+
+### 4. 错误处理和警告
+- 统一的错误信息存储
+- 警告信息收集
+- 完整的上下文错误跟踪
+
+## 支持的搜索阶段
+
+```python
+class RequestContextStage(Enum):
+    TOTAL = "total_search"                    # 总搜索时间
+    QUERY_PARSING = "query_parsing"          # 查询解析
+    BOOLEAN_PARSING = "boolean_parsing"      # 布尔查询解析
+    QUERY_BUILDING = "query_building"        # ES查询构建
+    ELASTICSEARCH_SEARCH = "elasticsearch_search"  # ES搜索
+    RESULT_PROCESSING = "result_processing"  # 结果处理
+    RERANKING = "reranking"                  # 重排序
+```
+
+## 基本使用方法
+
+### 1. 创建RequestContext
+
+```python
+from context import create_request_context, RequestContext
+
+# 方式1: 使用工厂函数
+context = create_request_context(reqid="req-001", uid="user-123")
+
+# 方式2: 直接创建
+context = RequestContext(reqid="req-001", uid="user-123")
+
+# 方式3: 作为上下文管理器使用
+with create_request_context("req-002", "user-456") as context:
+    # 搜索逻辑
+    pass  # 自动记录性能摘要
+```
+
+### 2. 阶段计时
+
+```python
+from context import RequestContextStage
+
+# 开始计时
+context.start_stage(RequestContextStage.QUERY_PARSING)
+
+# 执行查询解析逻辑
+# parsed_query = query_parser.parse(query, context=context)
+
+# 结束计时
+duration = context.end_stage(RequestContextStage.QUERY_PARSING)
+print(f"查询解析耗时: {duration:.2f}ms")
+```
+
+### 3. 存储查询分析结果
+
+```python
+context.store_query_analysis(
+    original_query="红色连衣裙",
+    normalized_query="红色 连衣裙",
+    rewritten_query="红色 女 连衣裙",
+    detected_language="zh",
+    translations={"en": "red dress"},
+    query_vector=[0.1, 0.2, 0.3, ...],  # 如果有向量
+    is_simple_query=True
+)
+```
+
+### 4. 存储中间结果
+
+```python
+# 存储解析后的查询对象
+context.store_intermediate_result('parsed_query', parsed_query)
+
+# 存储ES查询DSL
+context.store_intermediate_result('es_query', es_query_dict)
+
+# 存储ES响应
+context.store_intermediate_result('es_response', es_response)
+
+# 存储处理后的结果
+context.store_intermediate_result('processed_hits', hits)
+```
+
+### 5. 错误处理和警告
+
+```python
+try:
+    # 可能出错的操作
+    risky_operation()
+except Exception as e:
+    context.set_error(e)
+
+# 添加警告信息
+context.add_warning("查询结果较少，建议放宽搜索条件")
+
+# 检查是否有错误
+if context.has_error():
+    print(f"搜索出错: {context.metadata['error_info']}")
+```
+
+## 在Searcher中使用
+
+### 1. 自动创建Context（向后兼容）
+
+```python
+searcher = Searcher(config, es_client)
+
+# Searcher会自动创建RequestContext
+result = searcher.search(
+    query="无线蓝牙耳机",
+    size=10,
+    enable_embedding=True
+)
+
+# 结果中包含context信息
+print(result.context.get_summary())
+```
+
+### 2. 手动创建和传递Context
+
+```python
+# 创建自己的context
+context = create_request_context("my-req-001", "user-789")
+
+# 传递给searcher
+result = searcher.search(
+    query="运动鞋",
+    context=context  # 传递自定义context
+)
+
+# 使用context进行详细分析
+summary = context.get_summary()
+print(f"总耗时: {summary['performance']['total_duration_ms']:.1f}ms")
+```
+
+## 性能分析
+
+### 1. 获取性能摘要
+
+```python
+summary = context.get_summary()
+
+# 基本信息
+print(f"请求ID: {summary['request_info']['reqid']}")
+print(f"总耗时: {summary['performance']['total_duration_ms']:.1f}ms")
+
+# 各阶段耗时
+for stage, duration in summary['performance']['stage_timings_ms'].items():
+    percentage = summary['performance']['stage_percentages'].get(stage, 0)
+    print(f"{stage}: {duration:.1f}ms ({percentage:.1f}%)")
+
+# 查询分析信息
+query_info = summary['query_analysis']
+print(f"原查询: {query_info['original_query']}")
+print(f"重写查询: {query_info['rewritten_query']}")
+print(f"检测语言: {query_info['detected_language']}")
+```
+
+### 2. 识别性能瓶颈
+
+```python
+summary = context.get_summary()
+
+# 找出耗时超过20%的阶段
+bottlenecks = []
+for stage, percentage in summary['performance']['stage_percentages'].items():
+    if percentage > 20:
+        bottlenecks.append((stage, percentage))
+
+if bottlenecks:
+    print("性能瓶颈:")
+    for stage, percentage in bottlenecks:
+        print(f"  - {stage}: {percentage:.1f}%")
+```
+
+### 3. 自动性能日志
+
+RequestContext会在以下时机自动记录详细的性能摘要日志：
+
+- 上下文管理器退出时 (`with context:`)
+- 手动调用 `context.log_performance_summary()`
+- Searcher.search() 完成时
+
+日志格式示例：
+```
+[2024-01-01 10:30:45] [INFO] [request_context] 搜索请求性能摘要 | reqid: req-001 | 总耗时: 272.6ms | 阶段耗时: |   - query_parsing: 35.3ms (13.0%) |   - elasticsearch_search: 146.0ms (53.6%) |   - result_processing: 18.6ms (6.8%) | 查询: '红色连衣裙' -> '红色 女 连衣裙' (zh) | 结果: 156 hits ES查询: 2456 chars
+```
+
+## 线程安全
+
+RequestContext是线程安全的，支持并发请求处理。每个请求使用独立的context实例，互不干扰。
+
+```python
+import threading
+from context import create_request_context
+
+def worker(request_id, query):
+    context = create_request_context(request_id)
+    # 搜索逻辑
+    # context自动跟踪此线程的请求
+    pass
+
+# 多线程并发处理
+threads = []
+for i in range(5):
+    t = threading.Thread(target=worker, args=(f"req-{i}", f"query-{i}"))
+    threads.append(t)
+    t.start()
+
+for t in threads:
+    t.join()
+```
+
+## 调试支持
+
+### 1. 检查中间结果
+
+```python
+# 获取查询解析结果
+parsed_query = context.get_intermediate_result('parsed_query')
+
+# 获取ES查询DSL
+es_query = context.get_intermediate_result('es_query')
+
+# 获取ES响应
+es_response = context.get_intermediate_result('es_response')
+
+# 获取原始搜索结果
+raw_hits = context.get_intermediate_result('raw_hits')
+
+# 获取最终处理后的结果
+processed_hits = context.get_intermediate_result('processed_hits')
+```
+
+### 2. 错误诊断
+
+```python
+if context.has_error():
+    error_info = context.metadata['error_info']
+    print(f"错误类型: {error_info['type']}")
+    print(f"错误消息: {error_info['message']}")
+
+    # 检查是否有警告
+    if context.metadata['warnings']:
+        print("警告信息:")
+        for warning in context.metadata['warnings']:
+            print(f"  - {warning}")
+```
+
+## 最佳实践
+
+### 1. 统一使用Context
+
+```python
+# 推荐：在整个搜索流程中传递同一个context
+result = searcher.search(query, context=context)
+
+# 不推荐：在各个环节创建不同的context
+```
+
+### 2. 合理设置阶段边界
+
+```python
+# 只在有意义的大阶段之间计时
+context.start_stage(RequestContextStage.QUERY_PARSING)
+# 整个查询解析逻辑
+context.end_stage(RequestContextStage.QUERY_PARSING)
+
+# 避免在细粒度操作间频繁计时
+```
+
+### 3. 及时存储关键数据
+
+```python
+# 在每个阶段完成后及时存储结果
+context.store_intermediate_result('parsed_query', parsed_query)
+context.store_intermediate_result('es_query', es_query)
+
+# 便于后续调试和分析
+```
+
+### 4. 适当使用警告
+
+```python
+# 使用警告记录非致命问题
+if total_hits < 10:
+    context.add_warning("搜索结果较少，建议放宽搜索条件")
+
+if query_time > 5.0:
+    context.add_warning(f"查询耗时较长: {query_time:.1f}秒")
+```
+
+## 集成示例
+
+### API接口集成
+
+```python
+from flask import Flask, request, jsonify
+from context import create_request_context
+
+app = Flask(__name__)
+
+@app.route('/search')
+def api_search():
+    # 从请求中获取参数
+    query = request.args.get('q', '')
+    uid = request.args.get('uid', 'anonymous')
+
+    # 创建context
+    context = create_request_context(uid=uid)
+
+    try:
+        # 执行搜索
+        result = searcher.search(query, context=context)
+
+        # 返回结果（包含性能信息）
+        response = {
+            'results': result.to_dict(),
+            'performance': context.get_summary()['performance']
+        }
+
+        return jsonify(response)
+
+    except Exception as e:
+        context.set_error(e)
+        context.log_performance_summary()
+
+        return jsonify({
+            'error': str(e),
+            'request_id': context.reqid
+        }), 500
+```
+
+## 总结
+
+RequestContext提供了一个强大而灵活的框架，用于管理搜索请求的整个生命周期。通过统一的上下文管理、自动性能监控和详细的日志记录，它显著提升了搜索系统的可观测性和调试能力。
