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