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