• If you are trying to use Boolean operators, they must be ALL CAPS: kong heng ((chang han) OR (cheng han)) options ingo min ((clong yah) OR (hong tan)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "kong heng ((chang han) OR (cheng han)) options ingo min ((clong yah) or (hong tan)) ;*".
