Hmmm ... something's not meshing for me here. If I understood what you've said, you have a DbD index to which you are addIndexes'ing a memory index? I must have missed something, because addIndexes pre- and post-optimizes the target (Dbd) index, not the operand (mem) index.
I stand corrected. I'm using an IndexWriter opened on a RAMDirectory to do the indexing for a given transaction. Then I call addIndexes([writer]) on the IndexWriter backed by the DbDirectory to persist this. This approach ash turned out to be considerably faster and less noisy in the database (the amount of random access changes) than indexing into the DbDirectory backed index directly and then optimizing it.
The docs for addIndexes() say "After this completes, the index is optimized." I mistakenly thought that there was discussion here about making this no longer be the case.
