-----------------------------------

We can make the alive check query a "settable" in SolrJ. I'll put up a new PR 
for the same

> LBSolrClient.checkAZombieServer should be less stupid

> LBSolrClient.checkAZombieServer() currently does /select query for {{\*:\*}} 
> with distrib=false, rows=0, sort=\_docid\_ ... but this can still chew up a 
> lot of time if the shard is big, and it's not self evident wtf is going on in 
> the server logs.
> At a minimum, these requests should include some sort of tracing param to 
> identify the point of he query (ie: {{_zombieservercheck=true}}) and should 
> probably be changed to hit something like the /ping handler, or the node 
> status handler, or if it's important to folks that it do a "search" that 
> actaully uses the index searcher, then it should use  options like 
> timeAllowed / segmentTerminateEarly, and/or {{q=-\*:\*}} instead .. or maybe 
> a cusorMark ... something to make it not have the overhead of counting all 
> the hits.
