• Performing a fuzzy search may retrieve terms with similar spellings: so sach ky nang xa hoi. hieu hien bach nuoc va ((((dan di) OR (dan li))) or (dan de)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu hien bach nuoc va ((((dan di) OR (dan li))) OR (dan de)) cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu hien bach nuoc va ((((dan di) OR (dan li))) or (dan de)) cua tu*".
