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