Local code search tool 'ctx' combines BM25 and dense vectors

By PulseAugur Editorial · [1 sources] ·

The article details the inner workings of `ctx`, a TypeScript command-line tool designed for local code search. It explains how `ctx` combines BM25 lexical search with dense vector embeddings, fused using reciprocal rank fusion (RRF), to answer questions about codebases. The tool indexes local projects into SQLite and uses a local model served by Ollama, ensuring no cloud provider is involved in the data path. The process involves chunking files based on their type, with specific strategies for configuration files, Markdown, and programming languages like TypeScript, JavaScript, and Python, aiming to preserve exact identifiers and semantic meaning.

    What Hybrid Search Looks Like When It Has to Run on Your Laptop

    <p>Suppose you are working in a codebase you did not write, and you type the following question:</p> <blockquote> <p>Where is <code>ERR_CONN_RESET</code> handled?</p> </blockquote> <p>The answer exists. One file contains a <code>catch</code> block that checks for exactly that con…
