# 系統性文獻搜尋
## 描述
使用 MeSH 詞彙擴展和同義詞來執行完整的系統性搜尋,適合文獻回顧或需要全面涵蓋的研究。
## 觸發條件
- 「系統性搜尋」、「完整搜尋」、「文獻回顧」
- 「找所有關於...的論文」
- 「comprehensive search」、「systematic review」
- 提到 MeSH、同義詞、專業搜尋策略

## 工作流程
```
┌─────────────────────────────────────────────────────────────┐
│ Step 1: generate_search_queries(topic) │
│ → 取得 MeSH 詞彙 + 同義詞 + 建議查詢 │
└─────────────────────────┬───────────────────────────────────┘
│
┌─────────────────────────▼───────────────────────────────────┐
│ Step 2: search_literature() × N (並行執行多個策略) │
│ → 標題搜尋、標題/摘要、MeSH、同義詞搜尋 │
└─────────────────────────┬───────────────────────────────────┘
│
┌─────────────────────────▼───────────────────────────────────┐
│ Step 3: merge_search_results() │
│ → 合併 + 去重 + 標記高相關性文章 │
└─────────────────────────────────────────────────────────────┘
```

## Step 1: 產生搜尋素材
```python
generate_search_queries(topic="remimazolam ICU sedation")
```
### 回傳內容:
```json
{
"corrected_topic": "remimazolam icu sedation", // 拼字校正後
"mesh_terms": [
{
"input": "remimazolam",
"preferred": "remimazolam [Supplementary Concept]",
"synonyms": ["CNS 7056", "ONO 2745"]
},
{
"input": "sedation",
"preferred": "Deep Sedation",
"synonyms": ["Sedation, Deep", "Conscious Sedation"]
}
],
"all_synonyms": ["CNS 7056", "ONO 2745", "Sedation, Deep", ...],
"suggested_queries": [
{"id": "q1_title", "query": "(remimazolam icu sedation)[Title]"},
{"id": "q2_tiab", "query": "(remimazolam icu sedation)[Title/Abstract]"},
{"id": "q4_mesh", "query": "\"remimazolam [Supplementary Concept]\"[MeSH]"},
{"id": "q6_syn", "query": "(CNS 7056 OR ONO 2745)[Title/Abstract]"}
]
}
```
---
## Step 2: 並行執行搜尋
根據 `suggested_queries` 執行多個搜尋策略(並行!):
```python
# 並行執行這些搜尋
search_literature(query="(remimazolam icu sedation)[Title]")
search_literature(query="(remimazolam icu sedation)[Title/Abstract]")
search_literature(query='"remimazolam [Supplementary Concept]"[MeSH]')
search_literature(query="(CNS 7056 OR ONO 2745)[tiab]")
```
---
## Step 3: 合併結果
```python
merge_search_results(
results_json='[["12345","67890"],["67890","11111"],["11111","22222"]]'
)
```
### 回傳內容:
```json
{
"unique_pmids": ["12345", "67890", "11111", "22222"],
"high_relevance_pmids": ["67890", "11111"], // ⭐ 多個策略都找到的!
"statistics": {
"total_before_dedup": 6,
"total_after_dedup": 4,
"duplicates_removed": 2
}
}
```
**重點**: `high_relevance_pmids` 是最重要的論文,因為多種搜尋策略都找到它們!

## MeSH 擴展的價值
### 為什麼需要 MeSH?
| 使用者輸入 | PubMed 可能漏掉 | MeSH 會找到 |
|-----------|-----------------|------------|
| heart attack | Myocardial Infarction | ✅ 標準化詞彙 |
| sugar disease | Diabetes Mellitus | ✅ 標準化詞彙 |
| blood pressure drug | Antihypertensive Agents | ✅ 標準化詞彙 |
### Query Analysis 的價值
`generate_search_queries` 會顯示 PubMed 實際如何解讀你的查詢:
```json
{
"query": "(remimazolam AND sedation)",
"estimated_count": 561,
"pubmed_translation": "(\"remimazolam\"[Supplementary Concept] OR \"remimazolam\"[All Fields]) AND (\"sedate\"[All Fields] OR ...)"
}
```
你以為搜 2 個詞,PubMed 實際上擴展到 Supplementary Concept + synonyms!

## 搜尋策略選項
```python
# 全面搜尋(預設)
generate_search_queries(topic="...", strategy="comprehensive")
# 精準搜尋(加入 RCT 篩選)
generate_search_queries(topic="...", strategy="focused")
# 探索性搜尋(更多同義詞)
generate_search_queries(topic="...", strategy="exploratory")
```
---
## 進階臨床篩選 (Phase 2.1 新功能)
系統性搜尋可結合進階篩選:
```python
# 步驟 1: 產生搜尋素材
materials = generate_search_queries(topic="diabetes treatment elderly")
# 步驟 2: 執行搜尋,加入進階篩選
results = []
for sq in materials["suggested_queries"]:
r = search_literature(
query=sq["query"],
limit=50,
age_group="aged", # 只找老年人
species="humans", # 只找人類
clinical_query="therapy", # 治療研究
language="english" # 英文
)
results.append(r["pmids"])
# 步驟 3: 合併
merged = merge_search_results(results_json=json.dumps(results))
```
### 可用的進階篩選
| 篩選類型 | 參數 | 可用值 |
|---------|------|--------|
| 年齡群 | `age_group` | newborn, infant, child, adolescent, adult, aged, aged_80 |
| 性別 | `sex` | male, female |
| 物種 | `species` | humans, animals |
| 語言 | `language` | english, chinese, japanese, etc. |
| 臨床查詢 | `clinical_query` | therapy, diagnosis, prognosis, etiology |
---
## 完整範例
```python
# Step 1: 取得搜尋材料
materials = generate_search_queries(topic="machine learning diagnosis radiology")
# Step 2: 並行搜尋(使用 suggested_queries)
results = []
for sq in materials["suggested_queries"]:
r = search_literature(query=sq["query"], limit=50)
results.append(r["pmids"])
# Step 3: 合併
merged = merge_search_results(results_json=json.dumps(results))
# Step 4: 取得高相關性論文的詳情
fetch_article_details(pmids=",".join(merged["high_relevance_pmids"]))
```
---
## 結果不足時?
使用 `expand_search_queries` 來擴展搜尋:
```python
expand_search_queries(
topic="remimazolam ICU sedation",
existing_query_ids="q1_title,q2_tiab",
expansion_type="mesh" # 或 "broader" 或 "narrower"
)
```
- `mesh`: 使用更多 MeSH 同義詞
- `broader`: 放寬條件(OR 代替 AND)
- `narrower`: 加入篩選(RCT、近五年)
