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