Now I am confused, I must be missing something fundamental.  I take no action that I am aware of which closes the Reader, so how is it happening?  The attached code demonstrates the exception - please can you advise on what is happening under the covers?  :-)  

Thanks again,

: It turns out that the cause of the exceptions is in fact adding an item 
: twice - so you were correct right at the start :-)  I ran a test where I 

glad to see it all worked out.

: Just a minor point: isn't Lucence in a position to detect the duplicate 
: insertion attempt and flag it with something less vague than "Stream 
: closed"?  :-)

not really ... adding a document multiple times is a perfectly legal use 
case, adding a document with a "Reader" based field where the reader is 
already closed ... that's not legal (And Lucene doesn't really have any 
way of knowing if the Reader is closed because *it* closed it.
