The operator !! requires a term not to appear in the document results, and therefore all of the sentence results. This is useful if a user wants to exclude documents with a term from the search, no matter where they appear in those documents. The !! operator must immediately precede the query term, with no intervening white space, and there must be white space before the !! operator, as in:

clubs !!book

Since Oracle ATG Web Commerce Search applies morphology and term expansion by default, the !! operator applies to the original query index term plus all of its expansions. To exclude a literal term from the document results, use the double-quote operator with the !! operator, as in:

clubs !!"book"
