Guidelines: Filters

Inclusion of a search filter on this site is not an endorsement of its validity or a recommendation for its use by the editors of this site, by the InterTASC Information Specialists SubGroup or by the (UK) National Institute for Health and Care Excellence (NICE).

This page shows publications that have reviewed search filter performance and individual search filters.

Please note that other filter sites/filter collections may have relevant filters for this topic.

Individual search filters

Database indexing changes over time and new vocabulary may be introduced.  With older filters, please check the subject indexing to ensure that the subject indexing is still current and, if not, consider whether new vocabulary may need to be added to the filter. Please note that if filters are amended, the performance may change from that published in the original articles and the filter should be reported as amended from the original filter.
