• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) or (vu sach)) ky nang xa hoi. hieu ve chat tuc va ((thanh di) OR (thanh de)) cau theo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (vu sach)) ky nang xa hoi. hieu ve chat tuc va ((thanh di) OR (thanh de)) cau theo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) or (vu sach)) ky nang xa hoi. hieu ve chat tuc va ((thanh di) OR (thanh de)) cau theo".
• Adding a wildcard symbol may retrieve word variants: ((te sach) or (vu sach)) ky nang xa hoi. hieu ve chat tuc va ((thanh di) OR (thanh de)) cau theo*.
