• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) tang ma hoi. lieu va cac ((cuc ban) OR (cac ban)) thanh va va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sac ky)) tang ma hoi. lieu va cac ((cuc ban) OR (cac ban)) thanh va va triet".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sac ky)) tang ma hoi. lieu va cac ((cuc ban) OR (cac ban)) thanh va va triet*.
