• If you are trying to use Boolean operators, they must be ALL CAPS: ((o va) OR (so va)) tinh - hanh manh cua hang cong tan ((thanh cad) OR (hanh cad))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((o va) OR (so va)) tinh - hanh manh cua hang cong tan ((thanh cad) or (hanh cad))~".
• Adding a wildcard symbol may retrieve word variants: ((o va) OR (so va)) tinh - hanh manh cua hang cong tan ((thanh cad) or (hanh cad))*.
