Thank you all for responding to me. Due to some other activity, I was moved out of it and now I am on it. I tried to use ExtractingUpdateProcessorFactory but it seems to me that its support is not in Solr 4.5(which I am using) even not in any of the Solr version available in market. Pls. find the Apache development link:
ExtractingUpdateProcessorFactory: Currently under development in SOLR-1763 <https://issues.apache.org/jira/browse/SOLR-1763> Can you suggest me further? -- View this message in context: http://lucene.472066.n3.nabble.com/Indexing-on-plain-text-data-and-base64-encode-data-in-a-single-HTTP-POST-request-tp4097905p4105279.html Sent from the Solr - User mailing list archive at Nabble.com.
