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