Sample Database for Full Text Searching

Question

I am looking to do some benchmarking on Full Text Search indexes in PostgreSQL, SQLServer and Lucene.

Any ideas on where to find a good big sample database to perform queries against?

Thanks a lot in advance.

I think the great source would be wikipedia's database dump, since they contains really great amount of text. They are available here: http://dumps.wikimedia.org/

You could also try usenet archive, but there's harder to pick target language and the quality of language used is also lower.
