bq: By the way is there any way to see if there is a index for some particular field of a document?
not really conveniently. To know that you have to unwind the inverted index. The "luke" program can do this. Of course if the field is _stored_ it's easy, just return q=id:doc_id&fl=* Also note that in 6x, the above will work for returning the value form a docValues field even if the field isn't stored, https://cwiki.apache.org/confluence/display/solr/DocValues. Lots of background here: https://issues.apache.org/jira/browse/SOLR-8220.
