• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty dang ha noi. hieu van am thuc va ((kinh va) OR (sinh va)) ((cua te) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty dang ha noi. hieu van am thuc va ((kinh va) OR (sinh va)) ((cua te) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty dang ha noi. hieu van am thuc va ((kinh va) OR (sinh va)) ((cua te) or (cuu tre))".
