After 2,5 years of intensive research and programming efforts, the entire Openwebsearch.eu project team is excited to grant access to its pilot of the first-ever federated pan-European Open Web Index (OWI).
so… how do I search with it?
From what I can gather (it’s a government /academic computing project so it has to be as clear as mud), you can’t. They’re only making the index, which would allow other people to build a search engine using it.
Also while it’s “open”, they’re clearly intending to charge for commercial use:
Understand the differences between research and commercial licenses
not very open then…
probably open to anyone, not open source.
I envisioned an open thing where I could contribute by clustering my PC when idle to help scrape.
edit: but the search is public.
