• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky tang mai hoi. ((hieu ve) OR (hieu va)) cam tuc ((va xanh) OR (va hanh)) di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky tang mai hoi. ((hieu ve) or (hieu va)) cam tuc ((va xanh) OR (va hanh)) di cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky tang mai hoi. ((hieu ve) or (hieu va)) cam tuc ((va xanh) OR (va hanh)) di cua tre*.
