• If you are trying to use Boolean operators, they must be ALL CAPS: ((yan liang) OR (yang guang)) ((than china) OR (tuan china)) west yang's 2 longer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yang guang)) ((than china) OR (tuan china)) west yang's 2 longer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yang guang)) ((than china) OR (tuan china)) west yang's 2 longer a ;*.
