• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - ((thanh trung) OR (thanh tung)) ((ha nhung) OR (pha nhung)) cong tan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - ((thanh trung) OR (thanh tung)) ((ha nhung) or (pha nhung)) cong tan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - ((thanh trung) OR (thanh tung)) ((ha nhung) or (pha nhung)) cong tan toan tap*.
