Hound

Hound is a self-hosted source code search engine designed to index multiple repositories for high-performance regular expression queries. It serves as a multi-repository code indexer that provides a centralized interface for searching across large-scale, private, and versioned codebases.

The system utilizes trigram-based indexing to enable fast pattern matching and regular expression lookups without scanning every file. To maintain current search results, it employs automatic synchronization through a combination of periodic polling of remote version control systems and monitoring of local directory changes.

The platform supports private repository indexing by integrating with SSH keys and local mounted volumes. It aggregates data from disparate sources to facilitate cross-repository search functionality.

    Hound is a self-hosted code search engine that indexes source code repositories and provides fast regular expression search results using a trigram-based index. It is designed to be deployed on your own infrastructure, enabling you to search across multiple public and private code repositories simultaneously. The engine builds its search index by decomposing source code into three-character trigrams, which allows for fast substring matching with regular expressions. It supports searching across multiple repositories in parallel, returning results from the pre-built trigram index. Hound can in

    Codesearch is an indexed code search engine and large-scale source indexer designed to execute regular expressions across extensive source code trees. It functions as a tool for finding specific text patterns in large codebases by analyzing and indexing massive volumes of source files for rapid retrieval. The system utilizes a specialized trigram-based search index to accelerate complex regular expression queries. This indexing approach filters candidate documents via three-character sequences before applying full regular expression scans to ensure high performance on large datasets. The eng
