Hey Mike, That was a very useful response, also for long time Lucene users like myself who were stuck in legacy ways of doing things! I managed to easily change indexing of keys to DocValues and found myself wondering why I did not get anything returned, it appears indexing works transparent to any field, but to get your DocValue key out of the 'index' you need to use the AtomicReader... all now works like it did before, only faster (i hope ;-))
