# Enable the Phrase Index

The Content component phrase index stores short phrases from your index, for use with the `TermExpand` action phrase expansion.

TIP: The `TermExpand` phrase expansion, and the phrase index is also used by Query Manipulation Server (QMS) `TypeAhead` action in index mode to find phrases. For more information, refer to the Query Manipulation Server Reference.

The phrase index is not enabled by default, because it uses additional memory and on-disk storage, and adds overhead at index time. OpenText recommends that you enable the phrase index only if you want to use phrase expansion.

To enable the phrase index

1. Open the Content component configuration file in a text editor.

2. In the `[Server]` section, set `EnablePhraseIndex` to `True`.

3. Set any other optional parameters for the phrase index. For example, `PhraseIndexMaxTerms` controls the lengths of the phrases that Content stores (and therefore the length of the phrases is can expand).

   Other parameters (starting with the prefix `PhraseIndex`) control the memory usage for the phrase index, and the frequency that phrases must have in your index for them to be stored in the phrase index.

   For more information, refer to the Content component Reference.

4. Save and close the configuration file.

5. Restart the Content component for your changes to take effect.

TIP: To enable the phrase index in an existing Content index, you can set `RegeneratePhraseIndex` to generate the required phrase index files at startup.

For more information about `TermExpand`, refer to the Content component Reference.
