Hi,

First off, sorry about previous accidental post, had a sausage-fingered
moment.

Anyway...

If I merge two indices with CoreAdmin, as detailed here...

http://wiki.apache.org/solr/MergingSolrIndexes

What happens to duplicate documents between the two? i.e. those that have
the same unique key.

What decides which copy takes precedence? Will documents get indexed
multiple times, or will the second one just get skipped?

Also, does the behaviour vary between CoreAdmin and IndexMergeTool? This
thread from a couple of years ago:

http://web.archiveorange.com/archive/v/AAfXfQIiBU7vyQBt6qdk

suggests that IndexMergeTool can result in dupes, unless I'm
misinterpreting.

Thanks!

Andrew.
