• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - hanh trong van dong cong ban ((((hanh cau) OR (hanh cat))) OR (hanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc thieu xanh - hanh trong van dong cong ban ((((hanh cau) OR (hanh cat))) or (hanh cac))*".
