Semantic search is a search technology that understands the words of a query in context and produces results that are relevant to that context.
In Yext Search
Yext Search uses semantic search to process queries and return direct answers to users. Unlike traditional site search technology, which relies on index-based search to catalog a website's documents, Search pulls data from the entities stored in the Knowledge Graph — and the relationships between those entities — to answer users' queries in coherent, relevant ways.
