• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (yang xi))((png a) OR (peg a)) 1 recent changes a ((hong g) OR (zhong tai)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang xi))((png a) OR (peg a)) 1 recent changes a ((hong g) or (zhong tai)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang xi))((png a) OR (peg a)) 1 recent changes a ((hong g) or (zhong tai)) ;*.
