GIN Index with TEXT
Introduction In this article, we will continue to explore how to use GIN Index with the text data type First, please note that GIN Index only works with multi-valued data types, meaning fields containing multiple values, so you can easily create an index with the array type However, if you create a similar index with the text type, an error will be reported because text is only a single-valued type, containing only one content string, so you must pass an additional function that defines how to split the text value into items in an array before the index can be created If you remember, when using GIN Index with a text array, you will encounter limitations regarding partial search and must enter the exact word to search for it to work, now you can solve that problem by using text combined with two functions, to_tsvector and pg_trgm Full-Text Search This method uses the to_tsvector function and its index creation process will be as follows Tokenization & Normalization Split the text...
