• Performing a fuzzy search may retrieve terms with similar spellings: vu sach y nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (va cam)) thuc va huong 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 cai))) OR (va cam)) thuc va huong 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 cai))) or (va cam)) thuc va huong cua cua triet".
• Adding a wildcard symbol may retrieve word variants: vu sach y nang xa hoi. hieu ((((ve cam) OR (ve cai))) or (va cam)) thuc va huong cua cua triet*.
