In order to provide fast searching, JIRA creates an index of the text entered into issue fields. This index is stored on the file system, and updated whenever issue text is added or modified. It is sometimes necessary to regenerate this index manually; for instance, when you add a new custom field, or if the index is lost or corrupted.
Re-indexing is often needed after major configuration changes in Jira. Once certain fields have been created or modified in Jira, this could result in making the search index becoming out-of-sync Jira Instance configuration.
