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