• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ky) or (sac ky)) sang ma hoi. ((thu vien) OR (thu dien)) cac xuc ban hanh vi va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) sang ma hoi. ((thu vien) OR (thu dien)) cac xuc ban hanh vi va triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sac ky)) sang ma hoi. ((thu vien) OR (thu dien)) cac xuc ban hanh vi va triet*".
