Hardy Ferentschik commented on HSEARCH-121:
-------------------------------------------

I think you are right. In LuceneBackendQueueProcessor each LuceneWorker queue gets scanned for at least one job which has the isBatch flag set. If you have a mixed queue with say a few index additions and one optimization you would in fact execute the index optimization in batch mode (meaning that mergeFactor, maxMergeDocs and maxBufferedDocs would be set for the index writers). 

I don't think that this really matters. So far I couldn't find any information whether these parameters have any influence on optimization. One would assume that they don't.
