BioStudies Search: Find Studies and Datasets by Keyword

biostudies/study-search

Searches BioStudies (EMBL-EBI) by keyword and returns up to 20 hits per page: accession, type, title, authors, release date, view count and the number of files and links. Each hit carries a short `content` text snippet. `totalHits` may be approximate (`isTotalHitsExact` says so). EMBL-EBI BioStudies data, served by Eden Engine; not an official EMBL-EBI product.
