• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach cha me gioi con hong minh ) or ( thuat ((san xa) OR (dan xa)) me gioi bon cong thanh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach cha me gioi con hong minh ) OR ( thuat ((san xa) OR (dan xa)) me gioi bon cong thanh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach cha me gioi con hong minh ) or ( thuat ((san xa) OR (dan xa)) me gioi bon cong thanh ))".
• Adding a wildcard symbol may retrieve word variants: (( thu sach cha me gioi con hong minh ) or ( thuat ((san xa) OR (dan xa)) me gioi bon cong thanh ))*.
