Description
IndexWriter.forceMerge allows to force merges if the number of segments is higher than a configured limit. I would like to have the ability to also force a merge if there is a single segment in the directory. This is possible today by closing the IndexWriter, reopening with a custom merge policy such as UpgradeIndexMergePolicy, running a forceMerge and finally reopening again with the original merge policy but this is a bit impractical and if possible I would like to be able to do it without reopening the writer twice.
