• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) OR (sach tu)) lang ha noi. hieu ve cac xuc va thanh hai ((cua viet) or (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach tu)) lang ha noi. hieu ve cac xuc va thanh hai ((cua viet) OR (ca viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) OR (sach tu)) lang ha noi. hieu ve cac xuc va thanh hai ((cua viet) or (ca viet))".
• Adding a wildcard symbol may retrieve word variants: te ((sach ty) OR (sach tu)) lang ha noi. hieu ve cac xuc va thanh hai ((cua viet) or (ca viet))*.
