Search Engine

[ANtlord via Digitalmars-d-learn]

Good day! I recenlty have tried create typical project on vibe.d. 
The web framework is not bad. And I can say, that it is better 
that something another web frameworks. But I have met a problem. 
I can't find search engine.

I use xapian always. It has API for several languages, but except 
D. I know about another search engines, but I can't find even one 
for D. Does D have search engine? Or Have I find theme for 
starting open source project?

Best Regards. Sorry for my english.
