• If you are trying to use Boolean operators, they must be ALL CAPS: o cua tinh - hanh ((thang cua) OR (((tang cua) OR (mang cua)))) nhung cong dan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o cua tinh - hanh ((thang cua) or (((tang cua) OR (mang cua)))) nhung cong dan toan cao~".
• Adding a wildcard symbol may retrieve word variants: o cua tinh - hanh ((thang cua) or (((tang cua) OR (mang cua)))) nhung cong dan toan cao*.
