Hi,We are upgrading alfresco from 4.2 to 5.1. I followed the instructions from the below URL but there are lots of solr indexing errors after the upgrade.http://docs.alfresco.com/5.1/tasks/upgrade-process.html Did anyone upgraded successfully from 4.2 to 5.1?I see solr and solr4 in 5.1 whereas in 4.

Since Alfresco 5.0 SOLR4 is the recommended and the default. SOLR (without 4) is only contained as a legacy component to potentially support restricted search capabilities while SOLR4 builds a new index. It is very likely that changes in Alfresco 5.1 geared towards SOLR4 have been so extensive that SOLR can no longer index new / updated content properly.

So - switch to SOLR4 (the one from the 5.1 distribution) and drop SOLR.

Thanks very much for your help. I switched to solr4 and cleared the indexes and it looks fine now. I can now filter the documents.

I see dataformat exception in the logs, is this related to solr4 indexing?

Yes, this error very likely occurs during indexing when Alfresco tries to convert a PDF to plain text for full text indexing. The document metadata will still be indexed just fine, only the full text may not be searchable. Apparently a true type font is corrupt / not available.
