Subject merging Parallel indexes (can indexWriter.addIndexesNoOptimize be used?)
Date Tue, 03 Nov 2009 18:46:00 GMT

Given two parallel indexes which contain the same products but different
fields, one with slowly changing fields and one with fields which are
updated regularly: 

Is it possible to periodically merge these to form a single index?  (thereby
representing a frozen snapshot in time) 

For example: Can indexWriter.addIndexesNoOptimize handle this, or was it
(only) designed for merging shards? 
If not, is there another option (3rd party or not) to use, or would I have
to resort to low-level hacking?
