• If you are trying to use Boolean operators, they must be ALL CAPS: ((toc hieu) OR (toc thieu)) manh - hanh trung cua nhung huong dan ((toan ban) OR (than man))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((toc hieu) OR (toc thieu)) manh - hanh trung cua nhung huong dan ((toan ban) or (than man))~".
• Adding a wildcard symbol may retrieve word variants: ((toc hieu) OR (toc thieu)) manh - hanh trung cua nhung huong dan ((toan ban) or (than man))*.
