: aren't expandable at query time. It would be quite cool if Solr could do : query-time expansions of dynamic fields (e.g. hl.fl=page_*) however that : would require some knowledge of the dynamic fields already stored in the : index, which I don't think is currently available in either Solr or Lucene.
it is possible to get a list of all indexed fields from the underlying Lucence IndexReader, so it's certianly possible .. the notion of supporting "glob" syntax in all the situations where a list of field names is used has been talked about before, but no one has attempted a combrehensive patch yet. note the comments in this issue, and the two threads it links to... http://issues.apache.org/jira/browse/SOLR-247 -Hoss
