• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu sang ((ma hoi) OR (mai hoi)). hieu ((van cau) OR (van chat)) tuc va hanh via cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu sang ((ma hoi) OR (mai hoi)). hieu ((van cau) or (van chat)) tuc va hanh via cua tre~".
• Adding a wildcard symbol may retrieve word variants: thu cach tu sang ((ma hoi) OR (mai hoi)). hieu ((van cau) or (van chat)) tuc va hanh via cua tre*.
