• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien khanh) OR (chieu xanh)) - hanh san va thong cong ban ((than tap) OR (han tap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien khanh) or (chieu xanh)) - hanh san va thong cong ban ((than tap) OR (han tap))~".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien khanh) or (chieu xanh)) - hanh san va thong cong ban ((than tap) OR (han tap))*.
