• Performing a fuzzy search may retrieve terms with similar spellings: thu cach tu nano x hoi. hieu va ((cac xuc) OR (cac nuoc)) ((va hanh) or (ban hanh)) di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach tu nano x hoi. hieu va ((cac xuc) OR (cac nuoc)) ((va hanh) OR (ban hanh)) di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach tu nano x hoi. hieu va ((cac xuc) OR (cac nuoc)) ((va hanh) or (ban hanh)) di cua triet*".
