> Key: LUCENE-2886
> URL: https://issues.apache.org/jira/browse/LUCENE-2886
> Project: Lucene - Java
> Issue Type: New Feature
> Components: Codecs
> Reporter: Renaud Delbru
> Fix For: 4.0
>
> Attachments: LUCENE-2886.patch, LUCENE-2886.patch, LUCENE-2886.patch,
> LUCENE-2886_simple64.patch, LUCENE-2886_simple64_varint.patch,

>
> We could test the implementation of the Adaptive Frame Of Reference [1] on
> the lucene-4.0 branch.
> I am providing the source code of its implementation. Some work needs to be
> done, as this implementation is working on the old lucene-1458 branch.
> I will attach a tarball containing a running version (with tests) of the AFOR
> implementation, as well as the implementations of PFOR and of Simple64
> (simple family codec working on 64bits word) that has been used in the
> experiments in [1].
