## Tool Restriction (Critical)
ONLY use `web_search_advanced_exa` with `category: "research paper"`. Do NOT use other categories or tools.
## Full Filter Support
The `research paper` category supports ALL available parameters:
### Core
- `query` (required)
- `numResults`
- `type` ("auto", "fast", "deep", "neural")
### Domain filtering
- `includeDomains` (e.g., ["arxiv.org", "openreview.net"])
- `excludeDomains`
### Date filtering (ISO 8601)
- `startPublishedDate` / `endPublishedDate`
- `startCrawlDate` / `endCrawlDate`
### Text filtering
- `includeText` (must contain ALL)
- `excludeText` (exclude if ANY match)
**Array size restriction:** `includeText` and `excludeText` only support **single-item arrays**. Multi-item arrays (2+ items) cause 400 errors. To match multiple terms, put them in the `query` string or run separate searches.
### Content extraction
- `textMaxCharacters` / `contextMaxCharacters`
- `enableSummary` / `summaryQuery`
- `enableHighlights` / `highlightsNumSentences` / `highlightsPerUrl` / `highlightsQuery`
### Additional
- `userLocation`
- `moderation`
- `additionalQueries`
- `livecrawl` / `livecrawlTimeout`
- `subpages` / `subpageTarget`
## Token Isolation (Critical)
Never run Exa searches in main context. Always spawn Task agents:
- Agent calls `web_search_advanced_exa` with `category: "research paper"`
- Agent merges + deduplicates results before presenting
- Agent returns distilled output (brief markdown or compact JSON)
- Main context stays clean regardless of search volume
## When to Use
Use this category when you need:
- Academic papers from arXiv, OpenReview, PubMed, etc.
- Scientific research on specific topics
- Literature reviews with date filtering
- Papers containing specific methodologies or terms
## Examples
Recent papers on a topic:
```
