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