## AI overview

This deep dive explains ClickHouse's rebuilt full-text search implementation, including its column-oriented storage model, tokenization, inverted indexes, finite state transducers, posting lists, and redesigned query pipeline. It describes how the approach reduces I/O and improves search speed and space efficiency, while noting that the implementation described has been deprecated in favor of a newer implementation that was stated to be generally available and production ready as of March 2026.
