• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty dang xay hoi. hieu ve cham ((xuc ban) OR (quoc ban)) hanh vai ((cua triet) or (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty dang xay hoi. hieu ve cham ((xuc ban) OR (quoc ban)) hanh vai ((cua triet) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty dang xay hoi. hieu ve cham ((xuc ban) OR (quoc ban)) hanh vai ((cua triet) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: su sach ty dang xay hoi. hieu ve cham ((xuc ban) OR (quoc ban)) hanh vai ((cua triet) or (cua tu))*.
