Meanwhile I have completed the work on ioda fulltext engine. It is available from http://ioda.sourceforge.net/ including tools to archive a cur table from Wikipedias MySQL database.
A complete ready-to-run example, using a fully indexed de-wikipedia from Sept 8 2004, and including the binaries is available for download from: http://magnus.de/wikipedia/wikidemo.tar.bz2 (91 MB bz2). Unpack and run it for a performance test.
Cheers
