In this article, we will discuss “What is Jira re-indexing and why you should perform it”. 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. Please see How to Integrate Jira Software with GitHub Cloud, How to install and configure JIRA on Linux, and how to hide Folders and Files from Search Results in Windows.

Note: Support for Atlassian Server products ended on Feb. 15, 2024. Server products and apps no longer receive technical support, security updates, and bug fixes for vulnerabilities. Atlassian recommends migrating to the cloud and that remaining on Server is not recommended. This ensures you avoid costly data breaches and security risks. Unsupported licenses no longer have access to tech support, security updates, and bug fixes.

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.
