PostgreSQL Full Text Search is a flexible way to search documents stored in PostgreSQL database matching a given query. Latest versions of Postgres introduced several features, which makes FTS of jsonb documents more easy. I will talk about the use cases, the architecture of FTS and how to use its flexibility and configure for best performance. The talk will includes a data types, operators with indexes (GiST, GIN, Rum), phrase search, jsonb, jsonpath, dictionaries, discussion of some recent improvements and roadmap for future releases.
