• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ky sang ma hoi. hieu van chat xuc ((va hanh) or (((van hanh) OR (van anh)))) vai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky sang ma hoi. hieu van chat xuc ((va hanh) OR (((van hanh) OR (van anh)))) vai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky sang ma hoi. hieu van chat xuc ((va hanh) or (((van hanh) OR (van anh)))) vai cuu tre*".
