Xapian devel - Mar 2012 - GSoC 2012: Backend for Lucene format indexes

Hi All,
I'm Billy, a senior undergraduate student in Peking University. I'm
working
in the area of Information Retrieval and Web Mining. When going through the
idea list, I felt quite interested in the "Backend for Lucene format
indexes" project. I have been using java-lucene for about one year, but my
subsequent work prefers C++ codes. This project is very meaningful to
smooth the transition.
As far as I know, the operation of index file, e.g. IndexReader, has
changed quite some (Lucene3.5 File
Format<http://lucene.apache.org/core/old_versioned_docs/versions/3_5_0/fileformats.html#Index%20File%20Formats>)
, while the idea page itself still linked to an old 3.0
version<http://lucene.apache.org/core/old_versioned_docs/versions/3_0_3/fileformats.html>.
Since it doesn't seem a simple work to cope with all the versions, shall we
just implement to support the old 3.0 format, or a more stable version?
Thank you!

Thanks for noticing this - this idea was carried over from last year's
list, and that's why the link points to an old version.  I've updated
the link on the wiki to the newer one you gave above.

I think it makes sense to support the latest version as the priority,
with support for older versions possibly useful if there's time.

Cheers,
