I thought I may have found that with raindrop.io, but searching for a single specific string of text (like 'wine' in a HN URL of people discussing the 'wine' emulator) does not seemingly work with Raindrop. It seems that unless the string is in the URL title or description, the Bookmark service fails/isn't actually performing a full text search of a previously bookmarked page.
I’m working on an open-source social bookmarking site in Elixir that is API compatible with delicious/pinboard.
It’s named linkhut and it’s currently able to import your bookmarks from pinboard and browser exports. The flagship instance is: https://ln.ht
I’m still working on the archiving and full text search feature. I’ve been experimenting with different approaches and there’s still a few things I want to explore before settling on a solution.
I get that this is not really useful to you as of now, but if you still haven’t found anything in a couple of months, think about checking it out I might just have launched that feature by then.
I always recommend Zotero as a local/online bookmark manager. It does full text search, but you have to "save page as snapshot" and set search to "everything", for it to work
1. perfect support for 99% of websites, support import html, mhtml, webarchive.
2. full text search support、provide public api.
3. all functions are completely offline, no account registration, no credit card required, no information collected.
4. currently free in beta
5. support singlefile, singlefile can automatically save all pages viewed.
Browsers have bookmark searching; e.g. in Firefox use "* " (star space) before search terms to search bookmarks.
If you need a Web UI just get one of those analytics/BI freewares that works with Sqlite.
