Summary

In this chapter, we reviewed PostgreSQL's robust text-search features. Combined with PostgreSQL's increasing scalability, these capabilities enable developers to integrate SQL-based analytics with text search, creating a compelling, versatile business platform that integrates traditional SQL processing with various forms of text analytics. This not only helps keep it simple and avoid integrating third-party text-search solutions but also enables powerful business solutions that handle multilingual spelling, typos, auto-complete, and the analysis of large document sets.

This chapter focused on PostgreSQL's syntactical text-search capabilities (LIKE, regular expression, FTS, and trigrams). They find strings based on word similarity, not based on meaning.

In the following chapters, we will explore the use of AI and embeddings. Embeddings, represented as AI vectors, enable us to work with the semantics and meaning of polymorphic data, such as text and images...
