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