• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - hanh trung cap ((tong thong) OR (((dong thong) OR (dong thanh)))) dan toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - hanh trung cap ((tong thong) or (((dong thong) OR (dong thanh)))) dan toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - hanh trung cap ((tong thong) or (((dong thong) OR (dong thanh)))) dan toan tap*.
