ripgrep
ripgrep recursively searches directories for a regex pattern while respecting your gitignore
Project mention: fd: A simple, fast and user-friendly alternative to 'find' | news.ycombinator.com | 2025-03-19I'm sure you can get creative. :-) You can set an environment variable to control the encoding, expose a flag or any one of a number of other things to control the encoding.
You've also continued to ignore my most substantive rebuttal: that a specific example where ripgrep is not compatible with grep or doesn't behave the same doesn't mean it can't be used in shell pipelines. Literally nothing you've said has invalidated anything I've said. All you're doing is finding things that some implementations of grep can do that ripgrep (intentionally) cannot do in exactly the same way. But that's fine, because ripgrep was never, isn't and will never be compatible with grep: https://github.com/BurntSushi/ripgrep/blob/master/FAQ.md#pos...
So if you need grep compatibility get a fucking clue and just use grep.

MeiliSearch
A lightning-fast search engine API bringing AI-powered hybrid search to your sites and applications.
Project mention: Meilisearch – search engine API bringing AI-powered hybrid search | news.ycombinator.com | 2025-04-14Someone reported it, and I answered today [1]. It's a rule that is too hard on the front end, and we will fix it by using a better Hybrid search setup (not only semantic). Thank you for the report.

sonic
🦔 Fast, lightweight & schema-less search backend. An alternative to Elasticsearch that runs on a few MBs of RAM.
Sonic search https://github.com/valeriansaliou/sonic
Maybe not exactly the same, its a server that you can store documents and then retrieve their ID using a search string.

The amazing ast-grep tool does not support vue and scss by default but can be configured to do so.

I've been using McFly [1] recently, and like it a lot.
> McFly replaces your default ctrl-r shell history search with an intelligent search engine that takes into account your working directory and the context of recently executed commands. McFly's suggestions are prioritized in real time with a small neural network.

Project mention: Tantivy – full-text search engine library inspired by Apache Lucene | news.ycombinator.com | 2024-05-27
I ‘m using https://stork-search.net for my static website search, but it’s no longer maintained. So yeah, Tantivy would be a great candidate to replace it! :)

korvus
Korvus is a search SDK that unifies the entire RAG pipeline in a single database query. Built on top of Postgres with bindings for Python, JavaScript, Rust and C.
I find it misleading to use an f-string containing encoded `{CONTEXT}` <https://github.com/postgresml/korvus/blob/bce269a20a1dbea933...>, and after digging into TFM <https://postgresml.org/docs/open-source/korvus/guides/rag#si...> it seems in is not, in fact, an f-string artifact but rather the literal characters "{"+"CONTEXT"+"}" and are the same in all the language bindings?
IMHO it would be much clearer if you just used the normal %s for the "outer" string and left the implicit f-string syntax as it is, e.g.

Project mention: Oxidizing Ubuntu: adopting Rust utilities by default | news.ycombinator.com | 2025-03-21
And when you put people on a pedestal, they're guaranteed to let you down. :-) https://github.com/BurntSushi/aho-corasick/commit/474393be8d...
I wouldn't be surprised if that style of leak were more prevalent than one would expect. It's pretty subtle. But that link is the only such instance I'm aware of it happening to such a degree in crates I maintain. Maybe there are other instances. This is why I try to use `Box<[T]>` when possible, because you know that can't have extra capacity.
