• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach ty)) tang ma hoa. ((hieu van) OR (thien van)) cam tuc va thanh chi chua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sach ty)) tang ma hoa. ((hieu van) or (thien van)) cam tuc va thanh chi chua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sach ty)) tang ma hoa. ((hieu van) or (thien van)) cam tuc va thanh chi chua tre*.
