# EnablePhraseIndex

Set `EnablePhraseIndex` to `True` to store phrases to enable phrase expansion with the TermExpand action.

By default, IDOL Server stores terms, but it does not store multiple word phrases. You can enable the phrase index if you want to use multiple word phrase expansions, for example to provide type-ahead in queries by using Query Manipulation Server (QMS).

The phrase index uses additional memory and on-disk storage, and adds overhead at index time. Micro Focus recommends that you only enable phrase indexing if you want to use the new phrase expansion functionality.

You can populate the phrase index for an existing engine by setting `EnablePhraseIndex` and RegeneratePhraseIndex to `True`, and then restarting IDOL Server.
