# TermExpandParameter

When you have set Mode to `Index`, you can add the following parameters from the IDOL Server `TermExpand` action, to specify how it performs the expansion. Query Manipulation Server forwards these parameters to the IDOL Server data index.

- `Stemming`. Whether to return the list of terms in unstemmed form. By default, Query Manipulation Server sets `Stemming` to false.

- `Type`. The method to use to weight the term expansions. By default, Query Manipulation Server sets `Type` to DocOccs.

- `Expansion`. The method to use to expand the terms. By default, Query Manipulation Server sets `Type` to Wild.

- `FieldText`. Restrict term expansion results to terms that appear in documents that match the specified field text.

For more details about these parameters, refer to the IDOL Server Reference.

You can also add any additional parameters that you configure as AllowedQueryParams.
