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.
