• If you are trying to use Boolean operators, they must be ALL CAPS: toc cach tu nong ma hoa. hieu va cao duc manh ((hanh lai) OR (thanh lap)) ((cua tu) OR (su triet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc cach tu nong ma hoa. hieu va cao duc manh ((hanh lai) OR (thanh lap)) ((cua tu) or (su triet))~".
• Adding a wildcard symbol may retrieve word variants: toc cach tu nong ma hoa. hieu va cao duc manh ((hanh lai) OR (thanh lap)) ((cua tu) or (su triet))*.
