Synonym layer


A synonym layer is a component of a search engine that maps synonyms of search terms to the corresponding primary term, allowing search queries to be expanded and more comprehensive results to be returned.


The significance of a synonym layer lies in its ability to improve the relevance and coverage of search results by recognizing that different users may use different terms to describe the same concept. By mapping synonyms to primary terms, the search engine is able to capture a wider range of queries and return more relevant results.
