** PostgreSQL Enhances Text Search Capabilities with Full-Text Search Functions

The PostgreSQL database management system has introduced full-text search functions, offering advanced features for searching and ranking text data. This enhancement addresses limitations of traditional LIKE operators, enabling more complex searches and improved performance.

Full-text search functions, such as `to_tsvector()` and `to_tsquery()`, allow for tokenized versions of text data, facilitating comparisons and matching. These functions also enable lemmatization, which normalizes words by making them lower-case, removing suffixes, and stop words.

The new functionality is demonstrated with a YouTube video dataset, showcasing the creation of a searchable column using `to_tsvector()` and the use of GIN indexes for improved performance. The example illustrates the efficiency and flexibility of full-text search in PostgreSQL, outperforming traditional LIKE operators by up to 25 times.
