RetroFedHister: a private search engine [AIP]
https://github.com/asciimoo/hister
Hi everyone,
I am the original author of Searx. I started Hister with a similar motivation: reducing our dependence on external search engines while keeping searches and personal data under our control.
Searx is a metasearch engine that forwards queries to other search providers. Hister takes a different approach. It builds a private full text index from content you choose, then searches that index entirely on your own infrastructure.
Hister can automatically index pages through its Firefox and Chrome extensions. It can also watch local directories, import browser history and bookmarks, index individual URLs, and crawl complete documentation sites.
The feature I find most useful is offline previews. Hister stores the readable content and HTML of indexed pages locally. You can open a result in a clean and sanitized preview beside the search results without visiting the original website again.
Some other features:
- Full text search across web pages, PDFs, docx files, Markdown, OrgMode and text files
- Phrase searches, field filters, date filters, wildcards, negation, aliases, labels, facets, and result priorities
- Optional semantic search using an embeddings endpoint you configure
- Persistent website crawls
- Imports from browser history, Linkwarden, Karakeep, Shaarli, Wallabag, and Linkding
- Web, terminal, command line, HTTP API, and MCP interfaces
- SQLite and PostgreSQL support, plus optional multiple user hosting
Hister cannot replace a global search engine (yet) for subjects you have never encountered because it only searches what you have indexed. My workflow is to search Hister first, then use its shortcut to fall back to traditional search when I need broader web results.
The project is free software under the AGPLv3+ license. It can be installed as a standalone binary or with Docker.

SamsyInteresting, I didn’t see it in the documentation so if you didn’t document that already, you can have your local instance as search suggestion for Firefox on mobile and desktop. I use it for my own wiki, e.g. https://mastodon.pirateparty.be/@utopiah/116351732150481942
Also how I would imagine it is default search there and if no hit then fallback to a default search engine, e.g. DDG.

This is exactly how I use it. Hister has even a hotkey to quickly jump to your preferred online search engine with the current search query if you cannot find what you are looking for.

Not technically dictionaries but Kiwix does Wiki’s offline. Unfortunately its only the wiki’s they provide or you have to scrape yourself.
INeedManaFor that I use https://f-droid.org/packages/com.akylas.aard2
The slob dumps require a bit of hunting but other than that it works well for me
Free_AppalachiaThis looks really rad. I have been trying to build a leftist search engine using searxng and it has a lot of issue because of things getting blocked over tor due to the amount of background requests you have to be making to those sites. I have thought about building something like this to deal with that issue, but just had my hands full with other projects. Quite obviously (for those who like to come online to shit on really cool project people are building) the use case is people looking to build their own privately indexed search results without it having to get polluted by shit that comes up in other search engines. I feel like that was immediately apparent to me, because I have that use case and I immediately saw the utility here. For those who don’t get, just because it doesn’t fit the use case you have for internet related projects, doesn’t mean it’s not extremely useful to others. You literally don’t have to come on here just to shit on what other people are doing simply because, “you don’t get it.” This project looks really cool and I am going to look into replacing my searxng instance with this soon. I am super stoked that somebody has done this work. It has needed to be done for a long time. So thank you!
I don’t get it. It indexes pages which were already visited, right? So in order to find some website I need to first use another search engine. Afterwards, that website is in my browsing history and if I need it again, I don’t need to search for it. So what’s the use case for this project?
Your browsing history does not have full text search, so if you only remember the content of the page and not the title of it, you’re SOL. Or if you browse across multiple devices, you have to check multiple places to hope to find it.
It indexes pages which were already visited, right?
Yes, if you use the browser extension only, but Hister has an API and a crawler as well if you’d like to add content you have not visited yet. Also, Hister supports indexing local text files, not just websites.
Afterwards, that website is in my browsing history and if I need it again, I don’t need to search for it
- Unfortunately browser history does not include the page’s content only the URL + title combo at best.
- Browser’s can’t show an offline preview (Having offline previews is a huge privacy - and productivity - win in my opinion, it completely eliminates the need of creating external network requests)
These are the biggest weaknesses of the browser history compared to Hister, but there are many more nuances where Hister can provide extra features and QoL improvements. I recommend checking the documentation & posts on the website if you are interested in the details.
So does that mean that the index starts off as empty? If so, is there a way to create a centralized (I know that’s a bad word) starting repo such that the engine already knows some cool results? I have tabbed bookmarks for news that is not shitty, archives, video that isn’t YouTube, privacy resources, etc. It would be cool if people could post indices focused on certain topics that they could add. Like indices for random stuff, like dog grooming, kayaking, or woodworking. It could be a hub like Docker Hub, but for cool results.
Sorry. Ha ha. You know you have a good idea when people start asking for features. I haven’t even started it yet. Maybe I can try self hosting on my desktop.
This is exciting! I normally use Searxist on Android.
I’d absolutely love to do this! It’s already on my future plans list: https://hister.org/support :
Create infrastructure for importable, pre-indexed databases organized by topic, letting users quickly expand their local index with curated, relevant content.
It could be a hub like Docker Hub, but for cool results.
Exactly!

<3 No need to apologize. I appreciate suggestions a lot (especially if those are well aligned with my ideas =] ).
y0kai [he/him]this sounds really cool!
How did you come up with the name?
iirc “Hister” is the name of an evil despot used in at least one of Nostradamus’ “prophecies” and is often believed (by those who believe in these things) to be a reference to Hitler.
its also an ancient name for the River Danube, which flows through much of WWII’s battlefields
I thought it was obvious that “hister” was the verb-ificarion of the noun “history” since this thing is a service/tool which produces history.
Who cares what crackpot Nostradamus said. Nosferatu was more metal anyway 🤘
Ŝan • 𐑖ƨɤI’ve been slowly migrating from buku to hister, but it’s still early days. I do like þat hister indexes sites, which beats having to manually tag everyþing. So far it’s looking pretty good, þough. Þanks for writing it.
What are the Hardware requirements? I imagine the index will become quite large, no?
The storage requirement is around 100KB/page on average.
Memory usage can exceed 1GB momentarily for searches when using language detection and multi-language indexes (it is the default config). Without language detection Hister has a much smaller memory footprint (~30MB default with ~100-150MB peaks).

Any interested in making this a federated search?
I’ve been toying with the idea of a web-ring style search engine where it uses the fediverse’s post and sub system so that you can subscribe to “indexers” that are made by other users (or even mastodon users themselves) so that you can have highly targeted search engine systems. So, for example, you could make multiple search “scopes” and each of those scopes would follow specific other “sources” and search from them. Likewise, users could provide links and descriptions to add new entries to each scope which would, in essense, work like a fediverse post and then be distributed to all other interested parties.
I haven’t done a lick of implementation yet, but thought I’d share the idea here as I consider doing this more and more every day. The only thing I haven’t figured out yet is images, because ideally that would be a special type of scope view.
Federated search is the direction I’d like to go when the core is mature enough.
I’m still trying to figure out the best approach to make the federation secure (no accidental private/confidential data leak) and easy to use. Related conversations: https://github.com/asciimoo/hister/discussions/432 & https://github.com/asciimoo/hister/issues/387 . I’d appreciate help to figure out an optimal solution.
Already installed and loving this idea.
This seems super cool, you can curate your own search index :O
Being able to preview your search results offline is quite neat too!
One question though, how will you solve the issue of “echo chambers”, because from my understanding, it looks like it will only present results that you search for / have searched for, meaning for some people, you could be stuck with results that only support your view of the world.
I mean it kinda looks like that’s by design currently. It’s an indexer for your corners of the web, not a search aggregator to find new ones.
Exactly, the echo chamber phenomenon is mostly problematic for “discovery type” searches while Hister is mainly for “recall type” search.
Implementing federated search/index sharing could be a partial solution to this issue in the long run.
@asciimoo@lemmy.ml please update the title with the appropriate tag (rule 7) and if AI was involved in development, add the disclosure per rule 8 (sample disclosures can be found here)
Thanks!
Thanks for letting me know. I’ve updated the post.
Oh damn this could replace the bookmakers. I have Linkding with the Linkding Injector extension, but this would be next level.
You can view the saved text too, nice. Would it be possible to attach an HTML file from like single file for sites that have heavy image content as part of the “view” button? That’d completely replace Linkding/Karakeep/Linkwarden use cases for me
Understandable if not, that’s ancillary to the text search focus
The inspiration for Hister was a bookmarking app, but I realized that I always forget to manually trigger the bookmarking and I miss so many great resources.
Currently you can import SingleFile HTMLs using the
hister import filecommand, but no further integrations are implemented yet. Although, rendering the exact SinglePage file as a preview can be added relatively quickly. It would be also nice to accept files directly from the SingleFile extension.Thanks for the good suggestion, I’ve added it to my TODO! =]
I have tons of webpages saved using the Firefox built-in page saver, which saves and html file and a corresponding folder for the other resources (images, javascript). Would be cool if these could be imported as well. Though maybe the resource folder can be ignored and the html file can already be imported?
Asciimoo always with the cool stuff!
Think I’ll try getting it setup on Kubernetes and using it for searching documentation when programming.
Would you be interested in getting a Kubernetes example in the docs too then? If you have any requirements for it let me know.
