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