Thanks Eric. Here's the part which I'm not able to understand. I've for e.g. Source A, B, C and D in index. Each source contains "n" number of documents. Now, out of these, a bunch of documents in A and B are tagged with MediaType. I took the following steps:
1. Delete all documents tagged with MediaType for A and B. Documents from C and D are not touched. 2. Re-Index documents which were tagged with MediaType 3. Run Optimization Still, I keep seeing this exception. Does this mean, content from C and D are impacted even though they are not tagged with MediaType ? I'll follow your recommendation of creating a new collection, do a full index and delete original collection. -- View this message in context: http://lucene.472066.n3.nabble.com/Unexpected-docvalues-type-error-using-result-grouping-Use-UninvertingReader-or-index-with-docvalues-tp4218939p4219127.html Sent from the Solr - User mailing list archive at Nabble.com.
