Changing your luceneMatchVersion is unnecessary. We try to never make changes in the API or Solr behavior in a bugfix release, unless it's absolutely necessary to fix a bug. To my knowledge, changes in API and general behavior have NOT been required by any recent bugfix release. This means that a 4.8.1 match version will produce exactly the same results as a 4.8 match version. Changes in the index format are also avoided, so you will not need to reindex. The luceneMatchVersion code is capable of dealing with X.Y versions as well as LUCENE_XY ... Starting with 4.9, it also understands LUCENE_X_Y ... which was a required addition because version 4.10 wouldn't have worked with the LUCENE_XY notation. Thanks, Shawn
