Luke request handler issue

[Erik Hatcher]

I've switched Flare to use the Luke request handler simply to  
retrieve the fields in the index.

In the case of a 3.7M document index, it takes a LONG time to execute  
because of the top terms its generating.  I tried setting numTerms=0  
and got an array index out of bounds exception.  Is there a trick I'm  
not seeing in getting just the list of fields back in the fastest  
possible way with this request handler?

If Ryan is date-less again tonight, I'm sure he'll have it all fixed  
up by the time I wake up :)  Otherwise, I'll dig in and roll up my  
sleeves sometime this week and make some adjustments to allow turning  
off the top terms feature.

Thanks,
        Erik
