# Stemming

Set `Stemming` to `False` to turn off stemming. This parameter has an effect only when AdvancedSearch is set to `True` in the configuration file.

When you turn off stemming, IDOL Server does not stem the query terms before matching them against content in the index, so that only documents that contain exact matches for the query terms can return as results.
