Details

Unsplash's search API documentation describes the search capability as powered by both community-generated keyword tags and advanced image recognition. This recognition layer supplements manual and auto-generated tags to improve the relevance of search results. The system accepts text keyword queries as input and returns ranked photo results. Unsplash also confirmed in a 2021 year-in-review post that it tweaked its search algorithm to prioritize more diverse results.
