• Performing a fuzzy search may retrieve terms with similar spellings: thu cuc ky nang xa hoi. hieu van cam quoc va anh va ((cua triet) or (((cau tren) OR (ca tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cuc ky nang xa hoi. hieu van cam quoc va anh va ((cua triet) OR (((cau tren) OR (ca tren))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cuc ky nang xa hoi. hieu van cam quoc va anh va ((cua triet) or (((cau tren) OR (ca tren))))*".
