Building a Semantic Code Search Engine with LLMs

Sat, 11 Jan 2025 00:00:00 +0000

As developers, we spend a significant amount of time navigating large codebases. “Where is the authentication logic?” or “How does the payment flow work?” - these are questions we ask daily. Traditional text search falls short because it can’t understand intent. That’s why I built Code Scout.

The Problem

When joining a new project or revisiting an old one, understanding the codebase is often the biggest hurdle. You know what you’re looking for conceptually, but translating that into grep patterns or file names is tedious.

Overview

Code Scout is a semantic search engine that lets developers query large codebases using natural language. It goes beyond simple text matching to understand the intent behind your queries.

Key Features

Natural Language Search — Query your codebase using plain English questions like “Where is the authentication logic?” or “Find functions that handle file uploads”
Code Explanation — Get AI-powered explanations of complex code snippets
Diff Analysis — Understand changes between code versions
Standards Compliance Checking — Verify code against best practices and style guidelines
