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