Any Search Type
The any search type is supported by the GET /{custid}/titles endpoint. It can be used with any of the search fields. The any search type performs a "MATCH" query equivalent of an OR between each search term. The OR operator combines search terms so that each search result contains at least one of the terms. For example, use searchtype=any and search=sleep waking to find results that reference the terms sleep or the term waking.
