I'm using the PutSolrContentStream processor to push emails into my solrcloud. I understand that the processor is using the tika parser to extract fields from emails. How can i have these fields renamed or updated before pushing them to solr?
PutSolrContentStream processor is just streaming the data to solr. tika parser you are referring is on the solr side once data is pushed to solr. If you already have email mesage parsed say in JSON format you can update the json object before pushing it to solr.
