I am looking for a website similar to Google Search, where I can apply some custom reordering and filtering to the search results.
For example I'd like to deprioritize sites with commerce focus (possibly using some third party API to categorize the sites).
I know Google has a custom search engine but it doesn't seem to be what I want - it's for defining a search engine on a small subset of sites. Whereas I want one that scours the whole Internet, or at least the part Google sees already.
I can program websites and could feasibly build something like this myself, but I'm wondering if there is something already out there.
