I was going to add the detail that I was running 3.4 at the moment (I'm looking
to upgrade very soon) and thought
LogByteSizeMergePolicy was the default there, but I am wrong the actual code in
IndexWriterConfig is:
if (matchVersion.onOrAfter(Version.LUCENE_32)) {
mergePolicy = new TieredMergePolicy();
} else {
mergePolicy = new LogByteSizeMergePolicy();
}
3.4 would be the TieredMergePolicy which means the in-house operational merge I
saw was the result of Tiered (running with default settings), not the result of
LogByte.
