How PSNet Search Works

When you type a term into the Search function of AHRQ PSNet, the search algorithm searches resource titles, the author or publisher, and the full text of resources. The algorithm generates a score for each result based on where in the text a search term match is found. Matches to title words are given the highest score, followed by the author or publisher.
Three criteria determine how results are ranked when you browse AHRQ PSNet: (1) the significance and currency of the resource as determined by the AHRQ PSNet editorial team; (2) the relevance of the resource to the topic you are browsing; and (3) the publication date, with more recent resources weighted higher.
