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