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.comin 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.wroldorinstance: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:[[email protected]](/c/[email protected]). - Author -- Similar to the above you can also filter by a specific author such as:
author:@[email protected].
- Instance -- This will filter the results to only show communities that belong to a particular instance. Just type something like
- 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.
I think the use case and the default expectations about search are pretty different on Lemmy, but I can definitely see this being a potential point of friction, particularly since most content is actually structured by community rather than instance, and in many cases it would make more sense to exclude stuff based on the community it's posted to or the individual user than by instance. (But I'm sure that wouldn't be immediately technically feasible.)
Ya Lemmy organizes everything under a community technically. I mean I can filter on any piece of data I can get my hands on, but what makes the most sense. For MVP I chose to just grab whatever the API would give me. But then the question comes, if I do start filtering results, how do I determine what to actually exclude... long story short -- not an easy problem at least initially.
