• Performing a fuzzy search may retrieve terms with similar spellings: thuat ((lanh y) OR (anh y)) tang ma hoa. hieu ve cao duc ((tan anh) or (toan anh)) bai cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat ((lanh y) OR (anh y)) tang ma hoa. hieu ve cao duc ((tan anh) OR (toan anh)) bai cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((lanh y) OR (anh y)) tang ma hoa. hieu ve cao duc ((tan anh) or (toan anh)) bai cuu tre".
• Adding a wildcard symbol may retrieve word variants: thuat ((lanh y) OR (anh y)) tang ma hoa. hieu ve cao duc ((tan anh) or (toan anh)) bai cuu tre*.
