# Indexing in full-text search

In the data/information retrieval systems, **indexing** is the technique of creating a records structure that allows for **quicker retrieval of statistics**. 

In the case of **full-text search**, indexing involves creating a **structured catalog** of words or terms found in the text data, along with their corresponding locations.

The indexing process in full-text search is determined by the analyzer used. An analyzer is a component responsible for tokenizing the text, applying various transformations, and generating indexed terms.
