• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty dang xa hoi. hieu ve cac tuc ((van anh) or (van thanh)) ((tai cua) OR (thai cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty dang xa hoi. hieu ve cac tuc ((van anh) OR (van thanh)) ((tai cua) OR (thai cua)) triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty dang xa hoi. hieu ve cac tuc ((van anh) or (van thanh)) ((tai cua) OR (thai cua)) triet*".
