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