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