Full-Text Search ( FTS ) is a search for the documents, which satisfy query and, optionally, return them in some order. The most usual case is to find documents containing all query terms and return them in order of their similarity to the query. Notions of query and similarity are very flexible and depends on application. Document can live on a hard drive or to be completely virtual as a result of complex query.

I will explain the importance of built-in FTS, the basics of FTS (configurations, query language and indexes) and present several new feautures of PG12, which improve FTS.
