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