• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - ((hanh trong) OR (hinh trong)) ((qua dung) OR (quang dung)) luong quang tran cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - ((hanh trong) or (hinh trong)) ((qua dung) OR (quang dung)) luong quang tran cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh trong) or (hinh trong)) ((qua dung) OR (quang dung)) luong quang tran cao*.
