• Performing a fuzzy search may retrieve terms with similar spellings: su sach y lang xa hoi. hieu ke ((cau chuc) OR (cau chu)) va hanh ((tai cua) or (tri cua)) triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y lang xa hoi. hieu ke ((cau chuc) OR (cau chu)) va hanh ((tai cua) OR (tri cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y lang xa hoi. hieu ke ((cau chuc) OR (cau chu)) va hanh ((tai cua) or (tri cua)) triet".
• Adding a wildcard symbol may retrieve word variants: su sach y lang xa hoi. hieu ke ((cau chuc) OR (cau chu)) va hanh ((tai cua) or (tri cua)) triet*.
