Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| query | Yes | PubMed search query (supports full NCBI syntax) | |
| maxResults | No | Maximum results to return | |
| offset | No | Result offset for pagination (0-based) | |
| sort | No | Sort order: relevance (default), pub_date (newest first), author, or journal | relevance |
| dateRange | No | Filter by date range. The filter is applied only when both `minDate` and `maxDate` are non-empty; either one empty disables the entire date range. | |
| publicationTypes | No | Filter by publication type (e.g. "Review", "Clinical Trial", "Meta-Analysis"). Multiple values are OR'd — any match qualifies. | |
| author | No | Filter by author name (e.g. "Smith J") | |
| journal | No | Filter by journal name | |
| meshTerms | No | Filter by MeSH terms. Multiple terms are AND'd — all must match. | |
| language | No | Filter by language (e.g. "english") | |
| hasAbstract | No | Only include articles with abstracts | |
| freeFullText | No | Only include free full text articles | |
| species | No | Filter by species | |
| summaryCount | No | Fetch brief summaries for top N results (0 = PMIDs only) |
