• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang xa hoi. ((hieu va) OR (lieu va)) cham xuc ((van ban) OR (van thanh)) manh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang xa hoi. ((hieu va) OR (lieu va)) cham xuc ((van ban) or (van thanh)) manh cuu tre".
• Adding a wildcard symbol may retrieve word variants: thu sach ly nang xa hoi. ((hieu va) OR (lieu va)) cham xuc ((van ban) or (van thanh)) manh cuu tre*.
