• Performing a fuzzy search may retrieve terms with similar spellings: vu sach ky sang tai hai. hieu ve cac xuc ((((va hanh) OR (va danh))) or (va dan)) vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ky sang tai hai. hieu ve cac xuc ((((va hanh) OR (va danh))) OR (va dan)) vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky sang tai hai. hieu ve cac xuc ((((va hanh) OR (va danh))) or (va dan)) vi cua te".
• Adding a wildcard symbol may retrieve word variants: vu sach ky sang tai hai. hieu ve cac xuc ((((va hanh) OR (va danh))) or (va dan)) vi cua te*.
