• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) or (wang yong)) ((yan zi) or (yan zhi)) (rest or (test OR best)) yang tan kong sar ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yong)) ((yan zi) OR (yan zhi)) (rest OR (test OR best)) yang tan kong sar ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yong)) ((yan zi) or (yan zhi)) (rest or (test OR best)) yang tan kong sar ;*".
