• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky ((lang ha) or (nang x)) hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh tai cuc viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky ((lang ha) OR (nang x)) hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh tai cuc viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky ((lang ha) or (nang x)) hoi. ((hieu ve) OR (hieu va)) cam xuc va hanh tai cuc viet*".
