             Summary: Add back-compat indices for index sorting
                 Key: LUCENE-7561
                 URL: https://issues.apache.org/jira/browse/LUCENE-7561
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Michael McCandless
            Assignee: Michael McCandless


Index time sorting is a powerful feature making searches that are "congruent" with the sort much faster, in exchange for slower indexing.  For some use cases this is a great tradeoff.

We recently promoted the feature to core (LUCENE-6766) and made it very simple to use (you just call {{IndexWriterConfig.setIndexSort}}.  In LUCENE-7537 we are adding support for multi-valued fields.

I think it's important we properly test backwards compatibility and from a quick look it looks like we have no sorted indices in {{TestBackwardsCompatibility}} ...
