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