• Performing a fuzzy search may retrieve terms with similar spellings: te sach thu bang xa hoi. ((hieu va) or (hieu qua)) giao duc ((va hanh) OR (va danh)) lai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach thu bang xa hoi. ((hieu va) OR (hieu qua)) giao duc ((va hanh) OR (va danh)) lai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach thu bang xa hoi. ((hieu va) or (hieu qua)) giao duc ((va hanh) OR (va danh)) lai cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach thu bang xa hoi. ((hieu va) or (hieu qua)) giao duc ((va hanh) OR (va danh)) lai cua triet*.
