Codebase Indexing is the process of making a repository’s files, symbols, structure, and dependencies searchable, so an AI coding tool can retrieve the right context before it answers or edits.
It blends approaches: semantic search over Embeddings of code, lexical and symbol search, and structural signals like imports and call graphs. The goal is to surface the few files relevant to a task out of a repo far larger than any context window.
For builders it is the retrieval layer that decides whether Code Agents understand a large project or hallucinate its APIs. The hard parts are keeping the index fresh as code changes and chunking code along meaningful boundaries — functions and classes — rather than arbitrary line spans.
