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