Matches only items with scores equal to or exceeding the threshold.
The minimum score defaults to 0, which returns all matches. As the minimum score is increased above 0, up to a maximum of 1, the user of the grammar is indicating that matches must meet a higher confidence level for the match to be returned. If scoring is not used by the author of an entity, the minimum score parameter specified by the user has no effect, because by default the entity has a score of 1 and therefore is always be returned.
You can override the value of this parameter for specific actions by setting the MinScore action parameter.
