Thanks , for such search engine,that really includes no javascript and no cookies in any form.
Secondly Its amazingly fast, I believe its more than just C language. I tried different combinations of searches on your search engine to check whether results are being served from cache or so. And it looks all searches(don't know your cache/uncache db design) are several times faster comparable to many. + +1 for speed. Also i feel i found a minor bug.
Even though it looks passion project but don't know how long will you survive fighting DMCA ,others, costs without monetizing plans or accepting donations. Won't mind donation if you accept.
