Newbie question on Deduplication overWriteDupes flag

[aagrawal75 <aa...@gmail.com>]

I had a configuration where I had "overwriteDupes"=false. Result: I got
duplicate documents in the index. 

When I changed to "overwriteDupes"=false, the duplicate documents started
overwriting the older documents. 

How do I achieve, add if not there, fail if duplicate is found. I though
that "overwriteDupes"=false would do that.

A follow up question on this (as it is kind of new functionality).

What happens if several documents are submitted and one of them fails
due to that? Do they get rolled back or only one?

You can use the optimistic concurrency features to do this, by including a 
_version_=-1 field value in the document.

this will instruct solr that the update should only be processed if the 
document does not already exist...
