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