get filterCache in Component

[Markus Jelsma]

Hi,

We need to get the filterCache in a Component but 
SolrIndexSearcher.getCache(String name) does not return it. It seems the 
filterCache is not added to cacheMap and can therefore not be returned.

SolrCache<Query,DocSet> filterCache = 
rb.req.getSearcher().getCache("filterCache");

Will always return null. Can we get the filterCache via other means or should 
it be added to the cacheMap so getCache can return it?

Thanks,
Markus
