# EnableUniqueMatches

A Boolean that specifies whether to return only unique matches in each document. To return a single occurrence of a particular value, set this parameter to `True`. When `EnableUniqueMatches=True`, two `EntityN` definitions cannot return the same value, even if they use different patterns. If the same value occurs more than once, only the first instance is returned, even if the matches occur for different entities.

Duplicates display by default unless you set `EnableUniqueMatches` to `True` to explicitly remove them.
