• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) ((chat xuc) or (cam xuc)) va dinh va cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) ((chat xuc) OR (cam xuc)) va dinh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky lang xa hoi. ((hieu ve) OR (hieu va)) ((chat xuc) or (cam xuc)) va dinh va cua tre*".
