• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) OR (tran hoang))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) or (tran hoang))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - hanh trung cua nhung cong tan ((tran ban) or (tran hoang))*.
