Talend Studio provides a Synonym Index editor where you can have access to the Lucene index files. You can find these files in the root directory of Talend Studio in the following path /addons/data/synonym. This editor displays the entries and their related synonyms and provides you with several management icons.

For more information about the available data synonym dictionaries, see [Overview of the available indexes](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/overview-of-available-indexes).

You can also create such index files using the tSynonymOutput component.

Information noteNote: If the indexes were created with version 7.2 or lower, you need to update them. The location of the migration procedure depends on the Talend Studio installation:

* With the installer: /addons/scripts/Lucene\_Migration\_Tool/README.md
* With no installer: in the license email, click the link in *Migration tool for Lucene Indexes from version 4 to version 8*.
