It is unclear to me what you hope to accomplish by optimizing in this
case.  If you set MAX_MERGE_DOCS, lucene will produce a series of
segments of (approximately) that size, plus a bounded (log n) number
of additional segments, the sum of the size of which is <
MAX_MERGE_DOCS.  So at best you'd achieve one more segment merged.  I
doubt optimizing would buy you much, especially as num docs >>
