Maybe MetaGer if you can live with their quality
At the moment I am aware of two search engines available to me that doesn't try to drive me crazy by wasting my time on irrelevant results:
- kagi.com
- and search.marginalia.nu
and the second one, while being honest and high quality, has a rather limited index.
A directed effort toward unfucking query understanding and index execution is up next on the list of tasks to tackle though. Hopefully it'll make a decent impact.
