• Performing a fuzzy search may retrieve terms with similar spellings: te sach tu xang x hoi. hieu qua cac xuc va ((((hanh dai) OR (hanh tai))) or (van dai)) cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tu xang x hoi. hieu qua cac xuc va ((((hanh dai) OR (hanh tai))) OR (van dai)) cau tren*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tu xang x hoi. hieu qua cac xuc va ((((hanh dai) OR (hanh tai))) or (van dai)) cau tren*".
