• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach lo hang tai hoi. hieu ((ve chim) OR (van chat)) ((loc va) OR (luc va)) hanh va cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach lo hang tai hoi. hieu ((ve chim) or (van chat)) ((loc va) OR (luc va)) hanh va cua tre~".
• Adding a wildcard symbol may retrieve word variants: thu sach lo hang tai hoi. hieu ((ve chim) or (van chat)) ((loc va) OR (luc va)) hanh va cua tre*.
