------------------------------------------
The way we are using at Amazon scores are ignored and the query functions as a
filter. I think QueryCachingPolicy can be used to achieve this kind of thing?

> Hi,
> I'm part of the Amazon Lucene team. I was trying to get KNN queries to work
> with LRUQueryCache. From my understanding, if I have isCacheable to return
> true from my query class then it will taken care of. However, I want Lucene
> to only turn on the cache for KNN only and not for any other query like
> TermQuery, etc which might also be returning true for the isCacheable method.
> Is there any easy interface which would allow me to do this without having to
> go into each individual query class and returning false for the isCacheable
> for all of them or having to write my own cache class. Any help would be
> appreciated.
> Please correct me if I have incorrectly assumed something. This is my first
> issue!
>
> Thanks,
