I had a similar mapping, combining a string and a geo_point in a multi_field. ES does not complain when indexing or when creating the mapping but a geo query will fail. The problem is that in a multi_field, all fields must be of the same type, see http://www.elasticsearch.org/guide/reference/mapping/multi-field-type.html

I used the field type object instead of multi_field which allows querying as expected. http://www.elasticsearch.org/guide/reference/mapping/object-type.html
