Keeping "qt" parameter in distributed search

[Shawn Heisey <so...@elyograg.org>]

I have a request handler with a qt of "lbcheck" so that load balancer 
healthchecks, which happen every five seconds, do not skew my query 
statistics.

I've recently modified the way i do my load balancing, which required 
that I add a shards parameter to my PingRequestHandler.  The ping 
handler includes the qt parameter set to lbcheck, but when it is 
distributed to the shards, this gets lost, and it uses the standard 
handler.  Now my broker core is the only one with correct statistics.

Is there any way to preserve qt in a distributed search so this doesn't 
happen?  I am using Solr 1.4.1, but we are upgrading to 3.1-dev very soon.

Thanks,
Shawn

Thank you, Hoss, that was the secret ingredient!  It looks much better now.

I'm not very knowledgeable about how distributed searching deals with 
request handlers, url paths, and the qt param (i have no idea why the 
exact same handler isn't propograted to the remote shards by default -- i 
thought it was, but your email suggests that it isn't) but i have seen a 
"shards.qt" param mentioned on the list and in some tests.

It doesn't appear to be documented on the wiki anywhere, but you may want 
to search for it and see if it helps your situation.

(NOTE: posting your solrconfig.xml handler definitions and the example 
ULRs you are trying to load will help people understand the behavior you 
are seeing and give better assistence)
