[Foundation-l] building lucene-search-2 binary?

[Anon Sricharoenchai]

Hi,

Some question about lucene-search-2 binary,

1. Do I need apache's lucene library when building lucene-search-2 binary?
    Or it is already included in lucene-search-2 source tree?

2. Did lucene-search-2 in wikimedia (before migration to 2.1) use the
same binary as found in sourceforge,
    http://sourceforge.net/projects/lucene-search/files/ ?

3. Which version of lucene library is used to build binary found in
sourceforge and in wikimedia?

Best regards,
Anon.
