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