Retrievability is a term associated with the information retrieval of an information system, specifically a search engine or information retrieval system.

A document (or information object) has high retrievability, which is the result of the retrieval of the document by the search engine, and the document is likely to be of high quality. Conversely, if there are few things that retrieve the document, or when the document is retrieved, then the document has low retrievability.

Retrievability can be considered as one aspect of findability .

Applications of retrievability include detecting search engine bias , measuring algorithmic bias, evaluation of the influence of search technology, retrieval of information retrieval systems, and quality of documents in a collection .
