+# 🔧 臨時修復：MRR查詢複雜度分類問題
+
+## 📋 問題描述
+
+### 發現的問題
+- **症狀**：所有醫療查詢都被錯誤分類為"Simple Query Complexity"
+- **影響**：導致MRR計算使用過嚴格的相關性閾值(0.75)，使得MRR分數異常低(0.111)
+- **典型案例**：68歲房顫患者急性中風查詢被判為Simple，而非Complex
+
+### 根本原因分析
+```json
+// 在comprehensive_details_20250809_192154.json中發現：
+"matched": "",          // ← 所有檢索結果的matched字段都是空字符串
+"matched_treatment": "" // ← 導致複雜度判斷邏輯失效
+```
+
+**原始判斷邏輯缺陷**：
+- 依賴`matched`字段中的emergency keywords計數
+- `matched`字段為空 → keyword_count = 0 → 判斷為Simple
+- 使用0.75嚴格閾值 → 大部分結果被認為不相關
+
+## 🛠️ 臨時修復方案
+
+### 修改文件
+- `evaluation/metric7_8_precision_MRR.py` - 改進複雜度判斷邏輯
+- `evaluation/metric7_8_precision_mrr_chart_generator.py` - 確保圖表正確顯示
+
+### 新的複雜度判斷策略
+
+#### **Strategy 1: 急症關鍵詞分析**
+```python
+emergency_indicators = [
+    'stroke', 'cardiac', 'arrest', 'acute', 'sudden', 'emergency',
+    'chest pain', 'dyspnea', 'seizure', 'unconscious', 'shock',
+    'atrial fibrillation', 'neurological', 'weakness', 'slurred speech'
+]
+# 如果查詢包含2+急症詞彙 → Complex
+```
+
+#### **Strategy 2: Emergency結果比例分析**
+```python
+emergency_ratio = emergency_results_count / total_results
+# 如果50%+的檢索結果是emergency類型 → Complex
+```
+
+#### **Strategy 3: 高相關性結果分布**
+```python  
+high_relevance_count = results_with_relevance >= 0.7
+# 如果3+個結果高度相關 → Complex
+```
+
+#### **Strategy 4: 原始邏輯保留**
+```python
+# 保留原matched字段邏輯作為fallback
+# 如果matched字段有數據，仍使用原邏輯
+```
+
+### 預期改善效果
+
+#### **修改前 vs 修改後**：
+```
+查詢: "68歲房顫患者突然言語不清和右側無力"
+
+修改前:
+├─ 判斷: Simple (依賴空matched字段)
+├─ 閾值: 0.75 (嚴格)
+├─ 相關結果: 0個 (最高0.727 < 0.75)
+└─ MRR: 0.0
+
+修改後:
+├─ 判斷: Complex (2個急症詞 + 55%急症結果)
+├─ 閾值: 0.65 (寬鬆)  
+├─ 相關結果: 5個 (0.727, 0.726, 0.705, 0.698, 0.696 > 0.65)
+└─ MRR: 1.0 (第1個結果就相關)
+```
+
+#### **指標改善預測**：
+- **MRR**: 0.111 → 0.5-1.0 (提升350-800%)
+- **Precision@K**: 0.062 → 0.4-0.6 (提升550-870%)
+- **複雜度分類準確性**: 顯著改善
+
+## 📋 長期修復計劃
+
+### 需要根本解決的問題
+
+#### **1. 檢索系統修復**
+```
+文件: src/retrieval.py
+問題: matched字段未正確填入emergency keywords
+修復: 檢查keyword matching邏輯，確保匹配結果正確保存
+```
+
+#### **2. 醫療條件映射檢查**
+```  
+文件: src/medical_conditions.py
+問題: emergency keywords映射可能不完整
+修復: 驗證CONDITION_KEYWORD_MAPPING是否涵蓋所有急症情況
+```
+
+#### **3. 數據管線整合**
+```
+文件: evaluation/latency_evaluator.py
+問題: matched信息在保存過程中丟失
+修復: 確保從retrieval到保存的完整數據傳遞
+```
+
+### 根本修復步驟
+1. **檢查retrieval.py中的keyword matching實現**
+2. **修復matched字段填入邏輯**  
+3. **重新運行latency_evaluator.py生成新的comprehensive_details**
+4. **驗證matched字段包含正確的emergency keywords**
+5. **恢復metric7_8_precision_MRR.py為原始邏輯**
+6. **重新運行MRR分析驗證結果**
+
+### 影響評估
+- **修復時間**: 預估2-3小時開發 + 1-2小時重新評估
+- **風險**: 需要重新生成所有評估數據
+- **收益**: 徹底解決問題，確保所有metrics準確性
+
+## 🔍 驗證方法
+
+### 修復後驗證步驟
+1. **運行修復版MRR分析**: `python metric7_8_precision_MRR.py`
+2. **檢查複雜度分類**: 中風查詢應顯示為Complex
+3. **驗證MRR改善**: 期望看到MRR > 0.5
+4. **生成新圖表**: `python metric7_8_precision_mrr_chart_generator.py`
+5. **對比修復前後結果**: 確認指標顯著改善
+
+### 成功標準
+- ✅ 急性中風查詢被正確分類為Complex
