Lance Norskog commented on LUCENE-3491:
---------------------------------------
A couple of uses for this:
# Download index into a mobile device.
# Search index packaged with an ebook.
Both of these situations need "longevity of format version". Stuffing a verbose
format into a zip file should handle the data transmission problem. A suitable
C library should do basic searches in not very much space.
Lucene currently has no "mobile strategy". This would be a good toolkit.

> This issue presents the idea of a special-purpose Lucene index format that is
> suitable for cross-version compatibility and resilient to changes in Lucene
> implementations. Please see the attached document for more details.
> The code needs branch lucene-2621 to compile and run. It's still incomplete,
> in a roughly the same way as the Codec api is still incomplete ;) However, a
> separate tool PortableIndexExporter was implemented to illustrate how
> serialization of all index parts could look like.
> Comments and suggestions are welcome!
