• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - thanh vung tam nhung dung ((manh toan) OR (((thanh toan) OR (thanh san)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - thanh vung tam nhung dung ((manh toan) or (((thanh toan) OR (thanh san)))) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh vung tam nhung dung ((manh toan) or (((thanh toan) OR (thanh san)))) cau*.
