• Performing a fuzzy search may retrieve terms with similar spellings: ((((zhang yan) OR (wang yan))) or (dong sink)) ya hua (rest or test) tuan minh cong ghi ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((zhang yan) OR (wang yan))) OR (dong sink)) ya hua (rest OR test) tuan minh cong ghi ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((zhang yan) OR (wang yan))) or (dong sink)) ya hua (rest or test) tuan minh cong ghi ;*".
