Yes Erik I'm instantiating a new IndexSearcher for every search.
Then don't :) You only need a new IndexSearcher instance when the
index itself has changed.

I have slow subsequent searches.
And if i get the cache up and running is it persisted to disc?
No, Lucene's caches are not persisted, only in RAM. Are you using a
new IndexReader/IndexSearcher for your subsequent searches? If not,
you're likely not leveraging any caches at all.

I did a quite interesting notice, if i search for IndexId:x
(IndexId is unique) with a sort it still takes very long time,
which
it doesn't without the sort.
This will only be the case the first time you sort on a field
because
a FieldCache entry is created for that field and then cached for
subsequent sorts.
