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