Subject Re: How to read multiple indices in parallel.
Date Tue, 07 Apr 2015 14:27:24 GMT
Hi Terry,

I have multiple indices in separate locations. If I used multireader and
used an executorservice with the indexSearcher It will go thru the segments
in parallel and search right? But still searching between different indices
will happen sequentially..Isnt it?
