GET /searchstackexchange.com:mathoverflow-api
Searches MathOverflow questions by keywords in their titles. Returns questions matching the search terms with all their metadata. This is the primary text search endpoint — use it when looking for questions about specific mathematical concepts. For more complex queries including tag combinations, use `/search/advanced`.
Searches for questions by title and body content
- `site=mathoverflow` is required - `intitle` parameter searches for terms in question titles (space-separated = AND) - Does NOT search question bodies by default — use `/search/advanced` with `q` for full-text - Results are relevance-ranked by default - Combine with `tagged` to narrow by topic - Search terms are stemmed: 'homology' matches 'homological'
