But what happens when a query evaluated by the IndexReader/IndexSearcher 
mentioned in (1) results in a hit that has already been deleted by the 
second IndexReader? I.e. you try to access a document through one 
IndexReader that has already been deleted by another IndexReader.

I would expect some kind of exception because the document data can no 
longer be found, or am I missing something? I hope I am because your 
solution does sound very attractive ;)


Kind regards,

Chris
