• Performing a fuzzy search may retrieve terms with similar spellings: vu sac ky lang van hoc. ((hieu ve) OR (hieu va)) cac loc va tinh ((cao cua) or (ca cua)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky lang van hoc. ((hieu ve) OR (hieu va)) cac loc va tinh ((cao cua) OR (ca cua)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky lang van hoc. ((hieu ve) OR (hieu va)) cac loc va tinh ((cao cua) or (ca cua)) tre*".
