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.
Example of configuration details that might require these changes and return incorrect queries are as follows;
– Field configuration schemes
– Custom fields
– Plugins
– Time tracking
When this happens, a similar message as shown below will be displayed in your Administrative view.
***Someone** made configuration changes to 'SECTION' at TIME. It is recommended that you perform a re-index. It is recommended that you perform a re-index. For more information, please click the Help icon.
To perform the re-index now, please go to the 'Indexing' section.
Note: So that you only have to re-index once, you may wish to complete any other configuration changes before performing the re-index. To resolve this errors, simple re-index your jira instance.
– Note: A background re-indexing is advisable as this does not affect the system as users can continue working. After, indexing, remember to acknowledge.
