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