    Description

      An year ago I had started prototyping the upgrade to Lucene 5 [1], in the meantime version 6 (and 7 soon) has come out.
      I think it'd be very nice to upgrade Lucene version to the latest, this would give us improvements in space consumption and runtime performance.
      In case we want to upgrade to 6.0 or later we need to consider upgrade scenarios because Lucene Codecs are backward compatible with the previous major release, so Lucene 6 can read Lucene 5 but not Lucene 4.x (4.7 in our case) therefore we would need to detect that when reading an index and trigger reindexing using the new format.
      Related to that there's also a patch to upgrade Solr index to version 5 (see OAK-4318).
