    Citrus Search is a similarity-based search engine for scientific literature: select a paper, start the search and jump right to the heart of your research domain. Get an overview of important contributions from seminal papers to the state of the art. Searching for research with text queries can cumbersome: queries of just a couple of words are not a very high-fidelity signal, leading to lots of false positives in the search results. Also, you run the risk of missing papers which simply use different taxonomy than your query. This is where similarity-based search can be a great complement:…

    As a grad student (and an ADHDer), I had trouble doing literature review systematically. To combat this, I made a website that finds similar papers using the meaning of the thing I am looking for. I used MixedBread's [^1] embedding model to generate vectors from the abstracts. I store and search similar vectors using Milvus [^2] and finally use Gradio [^3] to serve the frontend. I update the vector database weekly by pulling the metadata dataset from Kaggle [^4]. To speed up the search process on my free oracle instance, I binarise the embeddings and use Hamming distance as a metric. I would…

    Built an automated system to run a deep search of ArXiv and carefully find all the precise papers that exist on a complex topic. It's different from simple RAG because it searches, classifies, and adapts based on relevant papers it uncovers, and then continues until it finds every paper on a topic (trying to mimic the human research process). Benchmarked 10x higher accuracy and total retrieval compared to Google Scholar for a median search (whitepaper on website). Also knows when it is complete, and misses virtually nothing (< 3% or so, once it's converged). Website has a free trial and a…

    Hey HN, Blog discovery is a problem [0] due to the decentralized nature of online writing. Everyone writes on their own site or platform, and there’s no central place that brings everything together. Google results prioritize large media publications over blogs, so we need something else. Blog Surf is an attempt to organize all of the great online writing done by individuals. I launched this project last year as a directory of personal blogs [1], but have now rebuilt it from scratch into a full-text search engine for blog posts. You can search for blog posts, and filter by publish date and…

    Much improved new version. Search for words similar to the query. For example, "death" will find "death", "dying", "dead", "killing"... Incredibly useful for exploring large text datasets where exact matches are too restrictive.

    Hi HN, As a researcher, I often found myself struggling with the limitations of keyword-based search when exploring PubMed papers. To address this, I created PubMed Search (https:&#x2F;&#x2F;www.pubmedisearch.com&#x2F;), a tool that leverages a vector database to enable semantic search across medical research literature. Some key features: * Daily updates to ensure access to the latest articles * Semantic search using latest & greatest embedding models * Some additional useful info about the papers (tldr, journal, publication date, etc.) Hope you find it useful!
