I shared bits and pieces of this before, but it’s officially up and running now: https://www.search-lemmy.com/

This is an enhanced search engine for Lemmy. With a few primary goals:

  • You can choose a preferred instance. After choosing what your primary instance is, and performing a search ALL links will open in that instance.
  • This aims to be a replacement for using site:reddit.com in Google, but just for the fediverse.
  • You can filter the search results by:
    • Instance – This will filter the results to only show communities that belong to a particular instance. Just type something like instance:lemmy.wrold or instance:https://lemmy.world/. This is separate from your preferred instance, such that you can search for posts on lemmy.world while still opening them on lemmy.ml.
    • Community – You can refine the search by a specific community. You use the same syntax that you’d use here community:!fediverse@lemmy.world.
    • Author – Similar to the above you can also filter by a specific author such as: author:@marsara9@lemmy.world.
  • The entire thing is open-source. You can view the code and even host your own instance… See more details here: https://github.com/marsara9/lemmy-search.

NOTE: This only supports Lemmy instances for now. Other fediverse type instances may be in the future depending on how this works out.

I’ve been working on this over just the last few weeks, so it hasn’t had a chance to crawl much of the fediverse yet. For now it only supports lemmy.world and lemmy.ml but other preferred-instances will come online as time goes by.

If anyone finds any bugs, and I’m sure you will, or if anyone has any suggestions PLEASE raise an issue on GitHub for me to track. Lastly, if anyone wants to help contribute please feel free to reach out.

NOTE TO SERVER ADMINS: You can prevent your site from being crawled by adding lemmy-search to your robots.txt for the user-agent.

      It searches the title and body. It also automatically searches for similar words like. Like ‘bike’, ‘biking’, ‘bikes’ (aka stemming). Granted though, I’m still improving the page ranking as time goes on.

      For micro/personal server runners

      Having to send out all those posts, comments, likes is killing the servers holding all the content. The project leaders really need to make an announcement about the performance problems, they are systemic.

      Correct. As I can only provide links to posts that are on your selected home instance. Eventually I’ll change this but you’ll get a 404 page for links that aren’t on your home instance, but see my P.S. below.

      P.s. there have been changes to the Lemmy API that have prevented me from getting updates for about a month now. So most of the results you’re seeing are from old posts only. Until I can rebuild the crawler or find a new API there won’t be any new content.

    This looks good, I just found an old (3 year old post - I didn’t even know Lemmy was around back then!) and commented on it. There were also funnily two other recent comments (one from 2 months ago and another 3 months old).

    Thanks for this! I was trying to figure out how to best replace the old “site:reddit.com” trick, and it did not quite work with lemmy with how it is federated. I hope that longer term we can get an “all” tab on lemmy that truly tries to pull from as many of the federated sites as possible to get us closer to the Reddit experience. I tried to do some research on extreme heat clothing due to the wet bulb temps in my area but r/mensfashion and most other clothing reddits still seemed private, maybe I can try searching with your solution now.

      Well, we were probably already due or going on past due for something to best replace the old “site:reddit.com” with “site:lemmy.world” for instance.

    make those results sort- and exportable (CSV, JSON, XML or the like), and you could be the new redditsearch.io. especially filtering results by different community/time/author would be great, and sorting by length/upvotes. what was that site with reddit post statistics called again? I know, this all might be further out, and wrangling bugs, the changing API and cloudflare might be more pressing issues, but maybe put it on the feature request list somewhere? all the best, and thank you for making this!

      There is a public API now. While I won’t support sorting, you can process and do what you will with the results as-is. Currently I only support Posts and Communities for now.

      When you search for posts you’re just matching against the title or body. For communities it’s searching the posts within that community.

      There’s also more filters now with: instance/community/author/since/until and a safe-search option.

      So I’m not sure how close this comes to your idea but I thought I’d share.
