• Performing a fuzzy search may retrieve terms with similar spellings: thuat thanh tay nang x hoi. ((hieu ve) OR (hieu va)) cau loc ((van hanh) or (va danh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat thanh tay nang x hoi. ((hieu ve) OR (hieu va)) cau loc ((van hanh) OR (va danh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat thanh tay nang x hoi. ((hieu ve) OR (hieu va)) cau loc ((van hanh) or (va danh)) vai cua tre*".
