• If you are trying to use Boolean operators, they must be ALL CAPS: doi ((chi hanh) OR (thi hanh)) - hanh trinh quan nhung ((cong vang) OR (cong quang)) tuan cu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chi hanh) or (thi hanh)) - hanh trinh quan nhung ((cong vang) OR (cong quang)) tuan cu~".
• Adding a wildcard symbol may retrieve word variants: doi ((chi hanh) or (thi hanh)) - hanh trinh quan nhung ((cong vang) OR (cong quang)) tuan cu*.
