Introducing Deep Search: A faster way to understand your code

Deep Search, now generally available, is a feature that enhances Code Search by allowing users to ask natural-language questions to better understand codebases, offering structured, navigable answers that are grounded in real code rather than just keyword matches. It is particularly useful for gaining overviews early in investigations, tracing logic across files or services, and obtaining summaries without manually piecing together results, complementing existing Code Search workflows that are more suited for finding specific code elements like functions or references. Deep Search leverages Sourcegraph's search and code navigation capabilities to run queries, follow references, and summarize findings, providing high-level insights into code functionality, such as authentication processes or error code triggers. Available in research preview for Enterprise Starter and Enterprise customers, Deep Search requires no additional cost until October 15th, 2025, although Enterprise-only customers must agree to new terms of service to access it.
