firstSearcher and newSearcher events

[Grant Ingersoll]

Is there a way, in a request, to know if the query being sent is from  
a firstSearcher event?  For instance, I've noticed that if one has the  
shards parameter in the firstSearcher call (I was just trying out some  
distributed stuff) it hangs Solr.

Presumably, we'd have to add a parameter to the request, right?  Just  
wasn't sure if there was some other low level setting that one could  
check.

Thanks,
Grant
