Show HN: A reactive search engine

I believe that a search engine without tracking and personalisation needs a better way to refine your search. This is what I am trying to build with Kligl.

You can click on any word in the snippet to add this word or remove pages that contain it. Clicking on a date should let you change to sorting by date, etc. - instead of searching for an option in the second page of the advanced search options.

Any feedback or feature requests are much appreciated.
