I am a computer geek with interest in Java, C#, and Apache Solr, business models, visualization and whatever else catches my fancy.

I wrote a book on Solr: http://bit.ly/ZPSSt4 and maintain useful Solr resources at http://www.solr-start.com/

comment How to write Solr query where it accepts multiple fileds returns the first non-null value in a list
You mean that you have already records indexed like that and reindexing is not an option? You are looking for pure query-time solution?

comment Solr dismax query returns no data, while standard query does
I suspect your problem was that you had no field title, so this was causing the problem. Try just that step of removing "title:" by itself.

comment Solr schema with nested object
Your schema.xml or managed-schema has a uniqueKey section that says what field it needs. In your case, it is probably says id but needs to say *MLId"

comment Solr not indexing files?
Are you sure you are looking at the right core in the Admin UI? OR perhaps you need to reload the UI page itself. Can you also include at least one of the actual 'sending files' lines showing what file extension and to what handler it went.

This is a question worth asking on the mailing list. Here, it is not very useful to anybody else, as it is too generic.

comment Unable to create core : _version_ field
This should NOT be the reason for the message. Perhaps there was an XML formatting error of some sorts as well.
