Sort by Relevance in PubMed
PubMed has added a new Display Settings option to sort your search results by relevance.
The relevance sort order for search results is based on an algorithm that analyzes each PubMed citation that includes the search terms. For each search query, “weight” is calculated for citations depending on how many search terms are found and in which fields they are found. In addition, recently-published articles are given a somewhat higher weight for sorting.
