runtime boost of differnet indexs in ParallelMultiSearcher

[Philip Peterson <be...@gmail.com>]

Hello,

Is there a way to, at run time, boost one index over another in a
ParallelMultiSearcher.

So if I have 4 indexes a,b,c,d and user A searches their results lean
toward index a
and user B searches his results are boosted toward index b etc.

Thanks so much in advance, 
I tried to see if there was any information on the in varius places
(including the GREAT book on lucene)

But I may have missed it.

thanks
Philip Peterson.

No, we don't cover this sort of thing in LIA.

One option is to create your own fork of ParallelMultiSearcher and  
boost the scores for the desired index in the relevant .search  
methods (excluding the HitCollector one).  It should be a minor tweak  
to accomplish this.  Maybe something general along these lines is  
worth adding to both MultiSearcher and ParallelMultiSearcher to allow  
a hook point for this?
