Hello everybody I think that is a dumb question, but I can't find the way to obtain some facets without an specific query, what I need is what is implemented for instance in blacklight's OPAC, a first screen that shows most common document types, most common subjects, most common etc. I'm planning to use it for exploring the collection, or could also use the most frequent subjects for making a dynamic tag cloud. I've seen one answer that points to use luke'sLucene index administration tool, but it seems to me something like violating the Solr "box".
Should I make a broad query like q=* and obtaining the facets? It's seems very expensive, isn't it? Thanks a lot for the help. Germán
