Heya,

while searching for the leak problem in my fst-suggest plugin I may have  
found it - I will do the change in my production system and see what  
happens possibly.

In order to get the IndexReader I use for the FSTSuggester I was calling

indexShard.searcher().searcher().getIndexReader()  
instead of  
indexShard.searcher().reader()

The release of the resources is called on indexShard.searcher().release()  
though

so, my question is - why are there two index readers to get? Where is the  
difference of those?

Thanks for enlightenment...

There isn't a different between the two readers, they are exactly the same.
