: I've been trying to return a field of type ExternalFileField in the search : result. Upon examining XMLWriter class, it seems like Solr can't do this out : of the box. Therefore, I've tried to hack Solr to enable this behaviour. : The goal is to call to ExternalFileField.getValueSource(SchemaField : field,QParser parser) in XMLWriter.writeDoc(String name, Document : document,...) method. There are two issues with doing this:
Some of what you're specificly asking about could probably be achieved by modifying the XMLWriter constructor to hang on to the SolrCore associated with the request. In general though i wondering if steping back a bit and modifying your request handler to use a SolrDocumentList where you've already flattened the ExternalFileField into each SolrDocument would be an easier approach -- then you wouldnt' need to modify the ResponseWriter at all. -Hoss
