Search papers
Search papers across the catalog. This is the primary discovery endpoint.
Does not count toward paper quota.
Search behavior (in order of precedence):
- Exact arXiv ID match:
1706.03762or1706.03762v7 - Full-text search on title + abstract
- Author name search (fallback)
- Fuzzy title match (last resort for typos)
