• If you are trying to use Boolean operators, they must be ALL CAPS: vu cac ky hoang van hoe. hieu ve cac ((luc va) OR (loc va)) ((thanh ca) OR (thanh cha)) cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu cac ky hoang van hoe. hieu ve cac ((luc va) OR (loc va)) ((thanh ca) or (thanh cha)) cua tre*".
