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