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
- For GitLab.com, exact code search is enabled in paid subscriptions.
- For GitLab self-managed, an administrator must install Zoekt and enable exact code search.
Zoekt search API
-
Introduced in GitLab 16.9 with a flag named
zoekt_search_api. Enabled by default.
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
-
Introduced in GitLab 16.11 with a flag named
zoekt_cross_namespace_search. Disabled by default.
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
-
Introduced in GitLab 16.8 with a flag named
zoekt_exact_search. Disabled by default. -
Generally available in GitLab 17.3. Feature flag
zoekt_exact_searchremoved.
GitLab has two search modes:

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 ().
