Use the operator property to modify the behavior of a match query:

→ "and": Any spaces between terms in the match property are interpreted as the AND operator. Documents must match all of the terms in the query.

→ "or": Any spaces between terms in the match property are interpreted as the OR operator. Documents must match at least one of the terms in the query.

For example, if you set a match property to the value "good great" and the operator property to "and", the Search Service only returns matches for documents that contain good and great.

If you set the operator property to "or", a document only needs to contain one of the terms from the match property: good or great.
