• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sac) OR (te san)) ky dang xay hoi. hieu van chat ((tu vay) OR (tuc va)) doan van cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) OR (te san)) ky dang xay hoi. hieu van chat ((tu vay) or (tuc va)) doan van cuu tre*".
