The indexes used by the Profiling perspective are available in a local file in the root directory of Talend Studio, in the following path \addons\data\synonym.

In each index file, you can find the following information:

* The index description
* The index structure
* An example
* The number of documents (words) in each index

You can access all these index files from the Profiling perspective using a Synonym Index editor. This editor displays the entries and their related synonyms and provides you with several management options.

You can use these indexes in certain data quality components, such as tSynonymSearch and tStandardizeRow. You can also create or update such index files using the tSynonymOutput component.
