I have a schema with a geolocation field named "author_geo" defined as
<field name="author_geo" type="location" indexed="true" stored="true" /> How can I list docs whose author_geo fields are not empty? Seems filter query "fq=author_geo:*" does not work like other fields which are string or text or float type. curl 'localhost/solr/select?q=*:*&rows=10&wt=json&indent=true&fq=author_geo:*&fl=author_geo' What's the right way of doing it? Thanks, Mingfeng
