Thank you Charlie, very informative even if non-scientific.
About the aggregations, are they very different from:
http://heliosearch.org/solr-facet-functions/ (obviously not yet
production ready)?
They're the same sort of thing. The ES significant terms aggregation is
particularly cool for spotting anomalies (look up Mark Harwood's blogs
and presentations on the subject). I think the new analytic capabilities
in Solr, Heliosearch and ES have some awesome potential.

Maybe Charlie Hull can answer that:
https://twitter.com/FlaxSearch/status/494859596117602304 . He seems to
think that - at least in some cases - Solr is faster.
I'll try to expand on the tweet.
Firstly, this is a totally unscientific comparison - we'd like to have time
to develop a proper public demonstration of some of the performance
differences we've found, which hopefully we will soon...so this is far more
anecdotal than statistical! Our eventual intention is to publicise any
differences so the wider community can tell us if we've done something
wrong, or maybe improve one or both engines. Don't get me wrong, we *like*
the fact there are two cool search server projects built on Lucene!
I can think of three recent projects where we've compared the two - we
wanted to be sure we were using the best fit for our clients:
1. a search over 40-50 million news stories with relatively complex
filtering requirements - Although ES promised more granular filtering it was
a lot slower to do it. We chose Solr.
2. a pretty standard intranet search over a few million items that might
require some clever visualisation in a future phase. No real difference in
speed, we chose ES.
3. a search over 700k items in the recruitment space with some geolocation
filtering - ES seemed to be faster at indexing, but Solr was a lot faster
for searching, and probably will be equivalent at indexing once we do some
tuning. We chose Solr.
Others have told me that if your documents are rich, choose Solr: if however
you have a large number of more simple documents, choose ES as the scaling
is less painful. If you like old-school XML config, choose Solr: if you're a
bearded hipster running a startup in Shoreditch choose ES. The aggregations
in ES are *way* cool.
YMMV, of course. The *only* sensible way to choose is to try both with your
data and requirements. Benchmarks are all very well, but they don't
necessarily apply to your situation.
Cheers
Charlie
I am also doing a talk and a book on Solr vs. ElasticSearch, but I am
not really planning to address those issues either, only the feature
comparisons.

I did see that earlier. My main concern is search
performance/scalability/throughput which unfortunately that article
didn't
address. Any benchmarks or comments about that?
We are already using SOLR but there has been a push to check
elasticsearch.
All the benchmarks I have seen are at least few years old.

This is quite an old discussion. Wanted to check any new comparisons
after
SOLR 4 especially with regards to performance/scalability/throughput?
