• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ty) or (sach tu)) hang ma hoi. hieu ve cham xuc ((xa dang) OR (da dang)) hai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ty) OR (sach tu)) hang ma hoi. hieu ve cham xuc ((xa dang) OR (da dang)) hai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ty) or (sach tu)) hang ma hoi. hieu ve cham xuc ((xa dang) OR (da dang)) hai cua triet*".
