• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) OR (vu bach)) ty nang ((o hoi) or (so hoc)). hieu van cam xuc va thanh lam su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu bach)) ty nang ((o hoi) OR (so hoc)). hieu van cam xuc va thanh lam su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) OR (vu bach)) ty nang ((o hoi) or (so hoc)). hieu van cam xuc va thanh lam su triet".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) OR (vu bach)) ty nang ((o hoi) or (so hoc)). hieu van cam xuc va thanh lam su triet*.
