• If you are trying to use Boolean operators, they must be ALL CAPS: toc cach tu lanh xa hoi. ((hieu van) OR (hieu va)) ((lam luc) OR (lao luc)) va hanh vai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc cach tu lanh xa hoi. ((hieu van) or (hieu va)) ((lam luc) OR (lao luc)) va hanh vai cua triet*".
