Release v1.36.0 🐙 · meilisearch/meilisearch Version v1.36.0 introduces an exciting update to the ranking rules to improve the engine's relevance. It's actually the first time we've made such a change since v1.0, and we're really happy about ...

✨ New: new ranking rules!

🔹 attributeRank → prioritizes matches in higher-weighted searchable attributes
🔹 wordPosition → prioritizes matches closer to the start of an attribute

Insert custom rules like price or date exactly where you want 🎯
Thanks @kerollmops.com!

And it has happened: Hegseth and Trump declare Anthropic a supply chain risk.

Every company that has government contracts will be barred from using Claude code.

It is an attempt to outright destroy the company because they did not consent to mass surveillance of Americans and AI kill bots.

Wow.

FOSDEM 2026 - Language support in Meilisearch

So cool 🤩 The @fosdem.org recording of Many is available. He talked about the language support and how we handle that in @meilisearch.com. I recommend it as a short start-of-the-weekend treat 🍬 fosdem.org/2026/schedul...

Retrieval Augmented Generation (RAG), Search, and Vector Databases How do you get your LLM to speak factually? Using Retrieval Augmented Generation (RAG).Learn all about RAG, search, and vector databases in this video! It complements a series of posts written in…

RAG conversations usually raise more questions than answers.
Luckily, we partnered up with Luis Serrano for this one. Luis is great at explaining complex stuff in simple terms.
If RAG is on your radar, give this a watch 👇

I added the option to output an emissive texture from the terrain generator. Here's a new moon to showcase the effect 🌋

I think Rust is very safe. In Meilisearch, with more than 200 contributors, we got two segfaults and one was a mistake in a wrapper around LMDB, a C library. It's been 8 years...

But a language is not only about the source code but also the ecosystem. Ada doesn't have cargo, the community nor the hype.

What are the benefits of Ada compared to Rust? It seems that Ada is not inherently memory safe compared to Rust

Nothing changes, that's still true 😅

Yes! Rust is better than C++ and one of the reasons is because it landed in the Linux Kernel. C++ tried and failed... #rustlang lwn.net/Articles/104...

From trees to graphs: speeding up vector search 10x with Hannoy This is a walkthrough of a new LMDB-based HNSW Rust vector store with drastically better performances than the previous random-projection-based one. This is a disk-based HNSW highly vector store inspi...

Hey 👋 It’s been a while! This morning, we published a new article about how we made @meilisearch.com’s semantic search much faster with hannoy. Hannoy is a new LMDB disk-based HNSW vector store that is much more perf. Now, it’s the default backend! #rustlang blog.kerollmops.com/from-trees-t...

Pagefind | Pagefind — Static low-bandwidth search at scale Pagefind is a fully static search library that aims to perform well on large sites, while using as little of your users’ bandwidth as possible, and without hosting any infrastructure.

Whoa, client-side search got good while I wasn't looking (and what a surprise, it's Rust)

So I have now tried btrfs, xfs, ext4 on two diff. SSDs, updating to Ubuntu 24; and I'm still getting corruptions... at this point I don't really know what to do.

This is not code specific (RocksDB is also affected), yet I don't understand how my OS and all apps just seem to continue to work fine...

Without having numbers (right now), LMDB will probably read absurdly fast, while not so much space- or write efficient.
Most, if not all data, fits into RAM here. Would be interesting to benchmark 100s of GBs.

But I found redb to be slower (sometimes much slower) than LMDB, pretty much always.

Have you figured out how heed/LMDB behaves on similar workloads? Because ReDB is highly inspired by it 👀

Thanks #EuroRust for the invite! I loved presenting with Nate on stage and don't forget: Just use Meilisearch! #rustlang #rust
