indexing - Is it possible to change the analyzer specified in the schema in Solr without reindexing from the original source?

Question

In Solr, if we have a field in the schema with stored="true", and we change the analyzer associated with that field, is it possible to update just this field without reindexing all the documents? Could this be done using the "stored" values of the field with the new analyzer without going back to the original data source?

Guy, I optimized your code.

    ...
    while (iter.hasNext()) {
        ...
        //server.deleteById(id) ;
        //server.commit() ;

        Collection<SolrInputDocument> docs = new ArrayList<SolrInputDocument>();
        docs.add(inputdoc) ;
        server.add(docs) ;
        // server.commit() ;
    }
    server.commit() ;
