• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sang)) - ((hanh trong) OR (anh trong)) cam thong cong tan toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (chieu sang)) - ((hanh trong) OR (anh trong)) cam thong cong tan toan ban*.
