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