• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((anh tang) OR (anh quang)) ((cua dung) OR (qua dung)) trong manh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - ((anh tang) or (anh quang)) ((cua dung) OR (qua dung)) trong manh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((anh tang) or (anh quang)) ((cua dung) OR (qua dung)) trong manh toan tap*.
