• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky tang ma hoi. hieu ((ve cam) or (va cam)) ((xuc va) OR (tuc va)) hanh vi khuan tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky tang ma hoi. hieu ((ve cam) OR (va cam)) ((xuc va) OR (tuc va)) hanh vi khuan tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang ma hoi. hieu ((ve cam) or (va cam)) ((xuc va) OR (tuc va)) hanh vi khuan tre*".
