• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. ((sieu viet) OR (su viet)) cac lo ((van anh) or (van thanh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. ((sieu viet) OR (su viet)) cac lo ((van anh) OR (van thanh)) vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. ((sieu viet) OR (su viet)) cac lo ((van anh) or (van thanh)) vai cua tre*".
