• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) OR (sach y)) ((lang xa) or (lang van)) hoi. hieu van cau tuc va danh dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sach y)) ((lang xa) OR (lang van)) hoi. hieu van cau tuc va danh dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) OR (sach y)) ((lang xa) or (lang van)) hoi. hieu van cau tuc va danh dai cua tre".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ky) OR (sach y)) ((lang xa) or (lang van)) hoi. hieu van cau tuc va danh dai cua tre*.
