Unary operator. Ensures that the term following NOT is excluded from all the returned documents. For example:
NOTE: NOT applies only to the term that immediately follows it. To exclude multiple terms, place them in brackets. To exclude a phrase, put the phrase in quotation marks and in brackets. For example:
Doc 1: I went to the city for the New Year
Doc 2: I went to New York City for the New Year
The following query does not match either of these documents:
action=Query&Text=city NOT (New York)
The following query matches the first document but not the second:
action=Query&Text=city NOT ("New York")
