The software is already open-source.

A free search API will be fully available probably next week. It's in testing already. It's just a matter of putting the finishing touches on the documentation.

And the crawl- and index-data will be available for download in a few weeks. It's also just a matter of documenting the data-format.

BTW: I disagree with your points about privacy. I see DeuSu as a way of fighting back.

How does the search / indexing compare to sphinx or lucene?

[deusu]

I don't know sphinx at all, and my knowledge of lucene is very limited. Which means I don't know how they would compare to DeuSu.

You should really have a look into both. I'm curious: Why did you create a new software from scratch if you do not know existing?

If you'd base a project on lucene/solr/elasticsearch or sphinx you'd also increase the chance of contributing to it.
