• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wing ian) OR (wing tan))) OR (hong tan)) ((yang jin) OR (yang xi)) test using a kong sar ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wing ian) OR (wing tan))) or (hong tan)) ((yang jin) or (yang xi)) test using a kong sar ;*".
