• If you are trying to use Boolean operators, they must be ALL CAPS: wang yanling liang zhi gene ((tan tan) OR (tas tan)) ((zhong tai) OR (hong ng)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling liang zhi gene ((tan tan) OR (tas tan)) ((zhong tai) or (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling liang zhi gene ((tan tan) OR (tas tan)) ((zhong tai) or (hong ng)) ;*.
