How to build a Code Search Engine
summary
A lightweight code search engine for small teams indexes GitLab projects, extracts every Python function with name, docstring, function and method calls, splits snake_case and CamelCase tokens, concatenates them into a document and builds a TF-IDF matrix so queries match at function granularity. A simple UI submits projects for indexing and returns repository links plus code snippets so teams find exact YAML or Python snippets quickly. Implementation is practical and demonstrated working on real repos as a prototype.
