Products that do what Fastest Prefix Search and Regex search in Lex Order does
I recently updated the benchmarking of Treds against RediSearch and the Redis Scan command for prefix searches. Treds continues to prove itself as the fastest prefix search server. It also supports fast regular expression matching, unlike Redis, which only offers limited glob pattern matching. Additionally, Treds returns results in sorted order. I’d love for you to check it out! If the modified Radix Tree approach interests you, consider starring the repository!

Hi all, I've talked about glidesort a few times on HN already, but it's finally ready for release. If you have any questions, feel free to ask. An academic paper on glidesort that goes into a lot more detail than the readme is upcoming, but is not ready yet. I will be giving a talk on glidesort tomorrow at FOSDEM 2023 in the Rust Devroom at 16:10, you can seek me out there as well. In other news, I am leaving academia soon, so if you have interesting (Rust) jobs the coming months feel free to approach me.

I want to share a really dumb, but very practical project I have packaged this summer, to perform operations on strings much faster. I was using Python to work with a multi-terabyte newline-delimited file. Reading, splitting, and shuffling it was a nightmare. So, I wrapped a trivial hardware-friendly heuristic I've been using for the last few years into a CPython library. The part I enjoyed the most is implementing SIMD behavior without SIMD instructions... Using 64-bit words to work at 8-bit granularity. Unlike conventional SIMD, the code would remain the same for ~~almost~~ any hardware.…

Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that…

Hi HN! I wrote a small program to browse folders in the terminal. The main inspiration was type-ahead search in GUI file managers. There exist several programs that are similar (see the listing in the README), but none of them do it quite the way I like, and often they have a very complex UI and a ton of features. I tried to make something that is obvious how to use and gets out of your way. (I also wanted an excuse to learn Rust.) Let me know what you think!

Hi! According to my benchmark tests I've just built the fastest free-text search engine in the world [0]. However, providing proof of that as well as making people care has proven to be a near impossible task. I could use some help from fellow programmers to both work on the formal proof but also to test this code against the Big5's offerings of full-text search. Would you care to go fetch an amount of common crawl data to test the abilities of ResinDB? If not, then do you perhaps have another strategy to convince people when you have invented something big? Is writing papers and formally…

Hey everyone, I have updated my fuzzy search library for the frontend. It now supports substring and prefix search, on top of fuzzy matching. It's fast, accurate, multilingual and has zero dependencies. GitHub: https://github.com/m31coding/fuzzy-search Live demo: https://www.m31coding.com/fuzzy-search-demo.html I would love to hear your feedback and any suggestions you may have for improving the library. Happy coding!

Hi everyone, I've made an open-source library for fast spatial search in Rust. It's called Spart, and it currently provides the following features: - Five tree implementations: Quadtree, Octree, Kd-tree, R-tree, and R*-tree - Python bindings (`pyspart` on PyPI) - Fast k-nearest neighbor (kNN) and radius search - Bulk data loading for efficient tree construction Project's GitHub repo: https://github.com/habedi/spart

This project presents a new data structure for storing ordered integer maps. The proposed data structure is a compressive, cache-friendly, radix tree that has performance comparable to an unordered map (`std::unordered_map`) and is an order of magnitude faster than an ordered map (`std::map`).

I built pg_textsearch, a Postgres extension that brings proper BM25 ranking to full-text search. It's designed for AI/RAG workloads where search quality directly impacts LLM output. Postgres native ts_rank lacks corpus-aware signals (no IDF, no TF saturation, no length normalization). This causes mediocre documents to rank above excellent matches, which matters when your LLM depends on retrieval quality. Quick example: CREATE EXTENSION pg_textsearch; CREATE INDEX articles_idx ON articles USING bm25(content); SELECT title, content to_bm25query('database performance', 'articles_idx') AS…

I kept re-Googling the same flags, so I built a tiny, fast directory of copy-ready CLI commands. It’s static (vanilla JS), instant search, keyboard nav (↑/↓ + Enter), favorites (localStorage), and linkable queries. Examples: • grep errors → https://www.greppers.com/?q=grep%20error%20logs • list open ports (macOS) → https://www.greppers.com/?q=list%20open%20ports • show git branch graph → https://www.greppers.com/?q=git%20graph • tail with colors → https://www.greppers.com/?q=tail%20colors Tech notes: static site on Netlify, no…
