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