• Performing a fuzzy search may retrieve terms with similar spellings: ((tu sach) or (thu sach)) ky nang xa hoi. hieu vien cau luc va ((hanh hoi) OR (hanh thoi)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu sach) OR (thu sach)) ky nang xa hoi. hieu vien cau luc va ((hanh hoi) OR (hanh thoi)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (thu sach)) ky nang xa hoi. hieu vien cau luc va ((hanh hoi) OR (hanh thoi)) cua tre".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (thu sach)) ky nang xa hoi. hieu vien cau luc va ((hanh hoi) OR (hanh thoi)) cua tre*.
