What I really want, is not another search engine for contextless queries. Except for really basic queries (which Google/etc already do a good job at), I'm trying to answer a question, perhaps open-ended, and it will take multiple queries to resolve. And it's not a linear process of narrowing down with + or - keywords. It's establishing a context: I'm searching for something relevant to "go" the language, not "go" the english verb or "go" the board game.

I want to be able to open a jupyter-like notebook with the start of my search query, and the first step should be to show me the available eigencontexts, from which I can establish the gross context for my entire search. After this first click, none of the results should be about the board game or the english word--unless the relevant search results happen to include an implementation of Go the board game in Go the language.

And then when I'm done, I want to name and archive that notebook so I can return to it at a later date--whether to refresh my memory of the ultimate answer, or to continue the search.

I guess I would call this a 'research engine' instead of a search engine.
