Yonik Seeley commented on SOLR-502:
-----------------------------------
I'm trying to think of Solr installations I've seen with problems, where this
would be the solution I would recommend... but I can't say I can think of any
(hence my hesitation, wondering if this is more of a solution in search of a
problem).
What is the underlying problem with some queries taking longer than others?
Is it more for the server side (don't spend too much time on any 1 query), or
for
the client side (control latency, even if result set is partial).
I *have* seen problems where queries started stacking up:

But this would not have fixed the problem.
If timeouts and partial results are expected to happen regularly (a non-trivial
% of queries), then one needs to start worrying about the bias introduced (it's
always low doc numbers that will be returned, which will be older documents if
one is doing incremental indexing). It seems like a better solution is to
increase hardware dedicated to the search collection.
If timeouts and partial results are expected to be rare, then it should have
little impact on the overall server load, so why worry about them?
Thoughts?
