• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach ky) or (sach y)) nang ma hoi. hieu vien bach le van anh gia ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ky) OR (sach y)) nang ma hoi. hieu vien bach le van anh gia ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ky) or (sach y)) nang ma hoi. hieu vien bach le van anh gia ((cua tre) OR (cuu tre))".
