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