pubmed-field-validator

PubMed field tag validation checks your search tags against official NCBI documentation to confirm they're syntactically correct and recognized. This prevents failed searches and ensures accurate results by catching common mistakes like incorrect capitalization or deprecated tags before query execution.

Common errors include using full-form tags like `[organism]` instead of short forms like `[orgn]`, or applying uppercase syntax. The validator identifies these mistakes, classifies them as invalid or deprecated, and suggests correct alternatives aligned with NCBI standards.

Yes, bulk validation scans your source code to find all used field tags and flags non-compliant usage in one pass. This identifies problematic tags across your project without manual inspection, then provides statuses and guidance for each tag found.

The validator checks tags against predefined dictionaries that distinguish valid, deprecated, and invalid tags. It returns a status for each tag with descriptive messages, letting you update code before deprecated tags stop working in NCBI queries.

PubMed field tags use short-form lowercase syntax without brackets in the validation process—for example, `ti` for title, `au` for author. The validator normalizes by stripping brackets and enforces lowercase to standardize your query construction.

No, the validator automatically checks field tags against the latest NCBI PubMed help documentation. This eliminates manual lookups and ensures your tags stay compliant without reviewing official docs repeatedly.
