• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sach y)) nang ma hoa. hieu ((ve cham) OR (vu cham)) luc va tinh lay cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (sach y)) nang ma hoa. hieu ((ve cham) OR (vu cham)) luc va tinh lay cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (sach y)) nang ma hoa. hieu ((ve cham) OR (vu cham)) luc va tinh lay cua tre*.
