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