I've got "<defaultSearchField>text</defaultSearchField>" and so if I do an unqualified search it only finds in the field text. If I want to search title, I can do "title:foo", but what if I want to find if the search term is in any field, or if it's in "text" or "title" or "concept" or "keywords"? I already tried "*:foo", but that throws an exception:
