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