IndexSearcher(IndexReader, IndexSearcherConfig) wouldn't be all that

Hi Ahmet,
The IndexSearcher is "thread-safe", it's just that the similarity field is
shared between threads. I think that to most people it is implied that the
similarity is not thread-local, as this would be surprising behavior.
Ideally the similarity field would not be mutable to indicate this,

"multiple threads can call any of its methods, concurrently"

Just had a glance at the IndexSearcher code.
Changing the similarity would not cause any failures. However the change
may not be immediately seen by all threads because the variable is
non-volatile (I'm open to correction on that...).
If you need multiple threads to have different Similarity impl
anyone?

Is this true for setSimilarity() method?
