If a single word is surrounded by double-quotes (for example, “books”), Oracle ATG Web Commerce Search interprets this as a literal constraint, meaning that the user wants the query term to match that word form and nothing else. Note that double-quotes do not enforce an alphabetic case match.
Double-quotes disable term expansion for the quoted term, meaning that the term can only match the same index term. Double-quotes also require that the morphological information of the query term be identical to the retrieved index term. For example, the term “books” is the index term book plus a +s suffix, so the query will retrieve results with the index term book, but it will filter those that do not have the +s suffix.
If a sequence of terms is quoted (for instance, “book clubs”), the terms are required to appear in the same order in the retrieved result as they do in the query, and to be adjacent to each other. For example, the quoted string “book clubs” would mean the following:
book must not be expanded and must match only this form of book, equivalent to the double-quoted query of “book”
clubs must not be expanded and must match only this form of club, equivalent to the double-quoted query of “clubs”
book and clubs must appear in that order in the retrieved result
book and clubs must be next to each other
For the adjacency constraint, intervening stop-words or punctuation do not count. For example, book – clubs and book a clubs would satisfy the example query.
