Exact code search

DETAILS: Tier: Premium, Ultimate Offering: GitLab.com, Self-managed Status: Beta

WARNING: This feature is in beta and subject to change without notice. For more information, see epic 9404.

With exact code search, you can use exact match and regular expression modes to search for code in all GitLab or in a specific project.

Exact code search is powered by Zoekt and is used by default in groups where the feature is enabled.

Enable exact code search

Zoekt search API

FLAG: The availability of this feature is controlled by a feature flag. For more information, see the history. This feature is available for testing, but not ready for production use.

With the Zoekt search API, you can use the search API for exact code search. If you want to use advanced search or basic search instead, see specify a search type.

By default, the Zoekt search API is disabled on GitLab.com to avoid breaking changes. To request access to this feature, contact GitLab.

Global code search

FLAG: The availability of this feature is controlled by a feature flag. For more information, see the history. This feature is available for testing, but not ready for production use.

Use this feature to search code across the entire GitLab instance.

Global code search does not perform well on large GitLab instances. When this feature is enabled for instances with more than 20,000 projects, your search might time out.

Search modes

GitLab has two search modes:

  • Exact match mode: returns results that exactly match the query.
  • Regular expression mode: supports regular and boolean expressions.

The exact match mode is used by default. To switch to the regular expression mode, to the right of the search box, select Use regular expression ({regular-expression}).

This table shows some example queries for exact match and regular expression modes.

Known issues

  • You can only search files smaller than 1 MB with less than 20_000 trigrams. For more information, see issue 455073.
  • You can use exact code search on the default branch of a project only. For more information, see issue 403307.
