• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ly) OR (sach y)) nang x ho. ((hieu ve) OR (hieu va)) cac xuc va danh vi lua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ly) OR (sach y)) nang x ho. ((hieu ve) or (hieu va)) cac xuc va danh vi lua tre".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ly) OR (sach y)) nang x ho. ((hieu ve) or (hieu va)) cac xuc va danh vi lua tre*.
