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