In April, NLM announced selected queries will no longer be updated (see: Update on PubMed Specialized Search Queries: Selected Queries No Longer Updated; Remain Available for Download and Customization). As these queries are no longer updated, the associated filters were removed from PubMed.

The last version of the selected PubMed Special Queries are available to use as a base to customize, update, and save as your own search strategies in My NCBI. To create your own search strategies, visit Saving and Managing Searches. There is also information and instructions on using MeSH and searching PubMed more effectively. For help with queries, please contact NLM Customer Support at https://support.nlm.nih.gov/.

In early December, the associated filters and subsets will be removed from the PubMed and NLM Catalog indexes during NLM’s Annual MEDLINE/PubMed Year-End-Processing activities.

After the Year-End-Processing update, these filters and subsets will no longer work when searched in PubMed or NLM Catalog as part of a query, such as: aids[sb], or jsubsetn.
