Thanks for the replies. I did look at caching but our commit time time is 90
seconds. It's definitely possible for someone to make a search, change the
page, and have wonky results. How about getting it to autowarm the x most
recent searches in the queryResultCache and that can hopefully reduce
If I'm searching for users based on last login time, and I search once, then
go to the second page with a new offset, I could potentially see the same
users on page 2 if the index has changed. What is the best way to anchor it
so I avoid this?

So the way I generate war files now is by running an 'ant dist' in the solr
folder. It generates the war fine and I get a build success, and then I
deploy it to tomcat and once again the logs show it was successful (from the
looks of it). However, when I go to 'myip:8080/solr/admin' I get an

need be but I'd like to avoid this. I'd rather do a full build from the

I'm wondering if the caches on all the slaves are replicated across (such as
queryResultCache). That is to say, if I hit one of my slaves and cache a
result, and I make a search later and that search happens to hit a different
slave, will that first cached result be available for use?
This is
Thanks for the informative response. I'll consider using the 'sticky'

because I'm actually doing more processing after the query component to come
up with my query result and I want to avoid that processing as much as

sort=sum(indexedField, constant). If I have a component that runs right
after the QueryComponent, is it possible to know what this value was for
each of the documents IF the field is not stored, and only indexed? I

Sorry for being vague. Okay so these scores exist on an external server and
they change often enough. The score for each returned user is actually
dependent on the user doing the searching (if I'm making the request, and
you make the same request, the scores are different). So what I'm doing is
Sorry for my ignorance, but do you have any lead in the code on where to look
for this? Also, I'd still need a way of finding out how long its been in
the cache because I don't want it to regenerate every time. I'd want it to
regenerate only if its been in the cache for less then 6 hours (or
It depends on how many queries you'd be making per second. I know for us, I
have a gradient of index sizes. The first machine, which gets hit most
often is about 2.5 gigs. Most of the queries would only ever need to hit
this index but then I have a bigger indices of about 5-10 gigs each which
I guess I'll have to use something other then SolrCache to get what I want
then. Or I could use SolrCache and just change the code (I've already done
so much of this anwyways...). Anyways thanks for the reply.

To clarify. I want to do this all underneath solr. I don't want to get a

Actually I was thinking I wanted to do something before the sharding (like in

Hmm, looks like I can inherit the Similarity Class and do my own thing there.

I actually have another question unrelated to this (but related to grouping).

There doesn't seem to be API to add a group (like group.field or group=true).
