• Performing a fuzzy search may retrieve terms with similar spellings: thuat anh y ((nang ma) or (nang cao)) hoi. ((hieu van) OR (hieu va)) bao suc van anh lai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat anh y ((nang ma) OR (nang cao)) hoi. ((hieu van) OR (hieu va)) bao suc van anh lai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat anh y ((nang ma) or (nang cao)) hoi. ((hieu van) OR (hieu va)) bao suc van anh lai cuu tre".
• Adding a wildcard symbol may retrieve word variants: thuat anh y ((nang ma) or (nang cao)) hoi. ((hieu van) OR (hieu va)) bao suc van anh lai cuu tre*.
