Update for PubMed's Best Match Sort
At the end of 2017, PubMed unveiled its updated Best Match sort order algorithm. Rather than sorting search results by publication date, Best Match allows you to sort by relevancy. The new algorithm incorporates machine learning to re-rank the top articles returned for improved relevance. This update builds on the original Best Match sort algorithm's term frequency ranking.
