      Description

      LUCENE-8962 added the ability to merge segments synchronously on commit. This isn't done by default and the default MergePolicy won't do it, but custom merge policies can take advantage of this. Solr allows plugging in custom merge policies, so if someone wants to make use of this feature they could, however, they need to set IndexWriterConfig.maxCommitMergeWaitSeconds to something greater than 0.
      Since this is an expert feature, I plan to document it only in javadoc and not the ref guide.
