Subject [jira] Resolved: (LUCENE-2232) Use VShort to encode positions
Date Fri, 19 Mar 2010 16:08:27 GMT


Paul Elschot resolved LUCENE-2232.

    Resolution: Not A Problem

The main advantage of changing the index formats nowadays comes from better compression, and
this patch gives a higher decoding speed at the cost of less compression, so it is probably
not worthwhile to pursue this any further.
