# Advanced Search Operators
|
|
|
|
## 매 한 줄
|
|
> **"매 search operator는 매 검색의 inverse index에 대한 직접 명령"**. 매 1990년대 boolean 검색에서 출발해 매 2026 LLM-augmented search (Perplexity, Claude search, GPT-5 browse) 시대에도 매 underlying engine은 여전히 operator-driven, 매 power user 의 productivity multiplier.
|
|
|
|
## 매 핵심
|
|
|
|
### 매 Operator 분류
|
|
- **Boolean**: `AND`, `OR`, `NOT` (or `-`) — 매 logical combination.
|
|
- **Phrase**: `"exact phrase"` — 매 token sequence 강제.
|
|
- **Field-restrict**: `site:`, `intitle:`, `inurl:`, `filetype:`, `intext:` — 매 specific field 검색.
|
|
- **Range / numeric**: `2020..2025`, `before:2026-01-01`, `after:2025-06-01`.
|
|
- **Wildcard**: `*` — 매 missing word.
|
|
- **Cache / archive**: `cache:`, `web.archive.org/web/*/url`.
|
|
|
|
### 매 엔진별 차이
|
|
- **Google**: 매 strict, `site:`, `filetype:`, `intitle:`, `before:`, `after:` 지원.
|
|
- **Bing**: `site:`, `language:`, `loc:`, `feed:`.
|
|
- **DuckDuckGo**: `!bang` (`!w wikipedia`, `!gh github`).
|
|
- **GitHub**: `repo:`, `path:`, `language:`, `extension:`, `is:issue is:open`.
|
|
- **Perplexity / Claude**: 매 natural language 도 OK 지만 매 explicit operator 가 더 reliable.
|
|
|
|
### 매 응용
|
|
1. **OSINT**: 매 leaked credential 검색 (`"@company.com" filetype:txt site:pastebin.com`).
|
|
2. **Research**: `site:arxiv.org "diffusion transformer" after:2025-01-01`.
|
|
3. **Debugging**: `site:stackoverflow.com [exact error message]`.
|
|
4. **Competitive intel**: `site:competitor.com filetype:pdf intitle:"roadmap"`.
|
|
|
|
## 💻 패턴
|
|
|
|
### Pattern 1: Site-restricted academic search
|
|
```
|
|
site:arxiv.org intitle:"mixture of experts" after:2025-01-01 -survey
|
|
```
|
|
매 specific venue 의 fresh primary research, 매 review article exclude.
|
|
|
|
### Pattern 2: GitHub code archaeology
|
|
```
|
|
repo:anthropics/claude-code path:**/*.ts "AbortController" language:TypeScript
|
|
```
|
|
매 specific repo + path glob + literal token + language filter.
|
|
|
|
### Pattern 3: Wayback Machine snapshot
|
|
```
|
|
https://web.archive.org/web/2024*/openai.com/pricing
|
|
```
|
|
매 historical pricing change track (매 2024 모든 snapshot).
|
|
|
|
### Pattern 4: Filetype hunt
|
|
```
|
|
"annual report" filetype:pdf site:tesla.com
|
|
```
|
|
매 specific document format 의 corporate disclosure.
|
|
|
|
### Pattern 5: Negative filtering
|
|
```
|
|
"react server components" -tutorial -beginner -"how to"
|
|
```
|
|
매 advanced content only, 매 entry-level material exclude.
|
|
|
|
### Pattern 6: Boolean composition
|
|
```
|
|
("vector database" OR "vector store") AND (pgvector OR qdrant) -benchmark
|
|
```
|
|
매 synonym expansion + scope narrowing.
|
|
|
|
### Pattern 7: Numeric range
|
|
```
|
|
"GPU memory" 40..80GB site:nvidia.com
|
|
```
|
|
매 spec range 검색.
|
|
|
|
### Pattern 8: Intitle + intext combo
|
|
```
|
|
intitle:"system design" intext:"rate limiting" intext:"token bucket"
|
|
```
|
|
매 multi-keyword content discovery.
|
|
|
|
### Pattern 9: Stack Overflow targeted
|
|
```
|
|
site:stackoverflow.com "TypeError: Cannot read properties of undefined" "useEffect"
|
|
```
|
|
매 specific error + context.
|
|
|
|
### Pattern 10: DDG bang chaining
|
|
```
|
|
!gh microsoft/vscode editor.contribution
|
|
```
|
|
매 instant redirect to GitHub 매 search.
|
|
|
|
## 매 결정 기준
|
|
| 상황 | Approach |
|
|
|---|---|
|
|
| 매 fresh research | `after:` + `site:arxiv.org` / `site:openreview.net` |
|
|
| 매 specific error | exact `"message"` + `site:stackoverflow.com` |
|
|
| 매 corporate intel | `filetype:pdf site:company.com` |
|
|
| 매 code search | GitHub `repo:` + `path:` + `language:` |
|
|
| 매 historical | Wayback `web.archive.org/web/<year>*/url` |
|
|
| 매 ambiguous topic | Boolean OR + negative filter |
|
|
|
|
**기본값**: 매 quoted phrase + `site:` + `after:` 조합 — 매 noise 의 80% 제거.

|
## 🤖 LLM 활용
|
|
**언제**: 매 LLM agent 가 web search tool 호출 시 — 매 explicit operator 로 query 작성하면 매 retrieval precision 급상승. 매 Claude / GPT-5 의 browse tool 도 매 underlying Google/Bing 사용 → operator pass-through.
|
|
**언제 X**: 매 conceptual / synthesis question — 매 LLM 이 직접 reasoning. 매 operator 는 매 specific document/fact retrieval 용.
|
|
|
|
## ❌ 안티패턴
|
|
- **너무 많은 operator**: 매 5개 이상 stacking 매 zero result. 매 progressive narrowing 의.
|
|
- **Quoted long phrase**: `"the quick brown fox jumps over"` — 매 too specific. 매 3-5 word key phrase 가 sweet spot.
|
|
- **`site:` over-restriction**: 매 single domain 만 보면 매 broader context 손실.
|
|
- **Stale cache reliance**: `cache:` 는 Google 에서 2024 deprecated — 매 web.archive.org 사용.
|
|
|
|
## 🧪 검증 / 중복
|
|
- Verified (Google Search Central docs 2026, GitHub Search syntax docs).
|
|
- 신뢰도 A.
