Is there a way in Solr 1.2 (or Solr 1.3) to update a single field of an existing document if I know the primary key? Reason I ask is that I construct a document from multiple sources and some fields may need periodic updating from one of those sources. I would prefer not to have to reconstruct the entire document (and hence query the multiple sources) for a single field change. I noticed that Solr 1.2 will delete and add the new document rather than replace individual fields. Is there a way around this?
Thanks Amit
