• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chu)) xanh - thanh trung cua thong thong dan ((han tap) OR (toan tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chu)) xanh - thanh trung cua thong thong dan ((han tap) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chu)) xanh - thanh trung cua thong thong dan ((han tap) OR (toan tap))*.
