Subject Re: [jira] Commented: (LUCENE-565) Supporting deleteDocuments in IndexWriter (Code and Performance Results Provided)
Date Tue, 12 Sep 2006 03:17:42 GMT
A strange case I just thought of.
Does the new code handle the case where a merge can drop the resulting
segment "down a level" (due to deletions)?

Example: M=3, B=10, maxMergeDocs=30

1) segment sizes = 30, 30, 30, 30
2) set maxMergeDocs=1000000
3) add enough docs to cause a merge
4) the leftmost 3 segments will be merged first, resulting in segment
sizes = 2, 30, n
