Thank you very much for your help Denis!
I have a question, what if there was a 'Museo Nacional de Antropología' at Guadalajara (a Mexico state), and another with the same name at Mexico City? How could I get just the one at Mexico city?, this because I am working with streets and commonly, streets from different places have the same name but different coordinates.
Thank you in advance.
