Sourcegraph 3.9: Literal search by default, multi-project LSIF code intelligence, Grafana dashboards, and configuration

Sourcegraph is the standard developer platform for code search and navigation at many of the largest and most advanced technology companies. With Sourcegraph, every company has access to the same kind of tools that Google and Facebook developers use every day.

We're excited to announce Sourcegraph 3.9. This release contains lots of behind-the-scenes work, both foundational and forward-looking.

Search queries are now literal (not regexp) by default

In Sourcegraph 3.9, search query terms are interpreted literally instead of as regular expressions by default. You can toggle this behavior using the .* icon in the search field.

We made this change to better match the expectations of most users (after a ton of feedback). Special characters such as *, (, and . are matched literally, so you can search for things like import { foo } or *MyType without needing to escape or quote your query.

Regular expressions are still supported, and we expect some users to prefer regexps for all of their queries. To default to regexp queries for a single user or for all users, set the search.defaultPatternType setting in user settings (/settings) or global settings (/site-admin/global-settings), respectively.

Other backcompat notes:

  • Existing saved searches will continue to work, retaining regexp interpretation.
  • API and CLI endpoints will continue to interpret search patterns as regexp. New API and CLI consumers can use the patternType flag in their queries to specify the desired behavior.
  • Browser omni bar search now defaults to literal search. To override this, use patternType:regexp in the query.
  • repo: and file: filters continue to accept regexps.

Cross-repository code change management

Keeping your code secure and up-to-date often requires making changes and merging pull requests across many repositories. As a step toward shipping support for large-scale code change campaigns, Sourcegraph now lets you track status and activity on campaigns of pull requests across repositories for GitHub and Bitbucket Server.

For example, if you've applied a critical security fix to 1,000 repositories, Sourcegraph makes it easy to see which and how many PRs are open/merged/closed, and you can monitor comments and review activity to see how to help get the fix approved and deployed.

Next, we plan to ship the ability to create branches and PRs across hundreds or thousands of repositories for common use cases (such as fixing security issues, upgrading dependencies, and refactoring usage of deprecated APIs).

Code change management campaigns are in private beta. Watch the code change management screencasts to see what we have planned, and apply for early access to this feature.

Monitor the health of your Sourcegraph instance

Sourcegraph's built-in monitoring with Grafana and Prometheus has been enhanced with default dashboards and alerts to help you confidently assess the health of your Sourcegraph instance. Sourcegraph is one of the most-used internal tools inside many large customers, and we've incorporated our learnings from these high-scale deployment environments. See monitoring and tracing documentation for more information.

LSIF-based code intelligence for multi-language repositories

LSIF-based code intelligence now works on repositories with multiple projects and languages. Languages currently supported for LSIF include Go, TypeScript, Python, and C/C++, with support for Java currently in development. Enable LSIF-powered code intelligence for your repositories by adding a simple step to your CI build process.

See the new site for list of languages with LSIF indexers (which means you can get precise, LSIF-based code intelligence on Sourcegraph).

Faster repository cloning on large instances

Sourcegraph now reacts more quickly to changes in the external services you configure (such as the code hosts to mirror repositories from). For example, when you add a new code host to Sourcegraph, its repositories will become available more quickly for searching and browsing.

(We made this improvement by applying external service updates in a streaming, not serial, fashion. Repositories are now added to Sourcegraph’s database and cloned immediately and one-by-one, instead of first loading the entire list of repositories from the code host and then syncing the entire list to the database. On large Sourcegraph instances that mirror 10,000s+ of repositories from code hosts, the first repositories will show up much more quickly than before.)

Export settings for easier bug reporting

Sourcegraph settings and configuration can now be viewed on a single page for easier exporting when reporting a bug. To view, go to ‘Report a bug’ on the site admin side panel or navigate to /site-admin/report-bug.

Note that secrets and tokens are not automatically redacted. Please review the full settings export before sharing externally.

Experimental paginated search API

To enable better programmatic consumption of search results, Sourcegraph 3.9 introduces the ability to consume an entire search result set via multiple paginated search requests. The results will be returned with a stable order. This new paginated search API is experimental and is not yet ready for production use, but we are eager to hear feedback from early adopters as we work to further improve it. (If you're interested, see the paginated search documentation and architecture design document)

Kubernetes: migration to using StatefulSets

For Sourcegraph users and customers that deploy using Kubernetes, our Kubernetes deployment manifest for indexed-search pods has changed from a Deployment to a StatefulSet. This is to enable future work on horizontally scaling indexed search.

To retain your existing indexes, follow the migration guide. If you upgrade without following these instructions, Sourcegraph’s indexed search will be temporarily unavailable (and overall search performance will suffer) while your code is reindexed.




  • Our external service syncing model will stream in new repositories to Sourcegraph. Previously we could only add a repository to our database and clone it once we had synced all information from all external services (to detect deletions and renames). Now adding a repository to an external service configuration should be reflected much sooner, even on large instances. #5145
  • There is now an easy way for site admins to view and export settings and configuration when reporting a bug. The page for doing so is at /site-admin/report-bug, linked to from the site admin side panel under "Report a bug".
  • An experimental search pagination API to enable better programmatic consumption of search results is now available to try. For more details and known limitations see the documentation.
  • Search queries can now be interpreted literally.

    • There is now a dot-star icon in the search input bar to toggle the pattern type of a query between regexp and literal.
    • There is a new search.defaultPatternType setting to configure the default pattern type, regexp or literal, for searches.
    • There is a new patternType: search token which overrides the search.defaultPatternType setting, and the active state of the dot-star icon in determining the pattern type of the query.
  • Added support for GitHub organization webhooks to enable faster updates of metadata used by campaigns, such as pull requests or issue comments. See the GitHub webhook documentation for instructions on how to enable webhooks.
  • Added burndown chart to visualize progress of campaigns.
  • Added ability to edit campaign titles and descriptions.


  • Recommended Kubernetes Migration: The Kubernetes deployment manifest for indexed-search pods has changed from a Deployment to a StatefulSet. This is to enable future work on horizontally scaling indexed search. To retain your existing indexes there is a migration guide.
  • Allow single trailing hyphen in usernames and org names #5680
  • Indexed search won't spam the logs on startup if the frontend API is not yet available. zoekt#30, #5866
  • Search query fields are now case insensitive. For example repoHasFile: will now be recognized, not just repohasfile:. #5168
  • Search queries are now interpreted literally by default, rather than as regular expressions. #5899
  • The search GraphQL API field now takes a two new optional parameters: version and patternType. version determines the search syntax version to use, and patternType determines the pattern type to use for the query. version defaults to "V1", which is regular expression searches by default, if not explicitly passed in. patternType overrides the pattern type determined by version.
  • Saved searches have been updated to support the new patternType filter. All existing saved searches have been updated to append patternType:regexp to the end of queries to ensure deterministic results regardless of the patternType configurations on an instance. All new saved searches are required to have a patternType: field in the query.
  • Allow text selection in search result headers (to allow for e.g. copying filenames)


  • Web app: Fix paths with special characters (#6050)
  • Fixed an issue that rendered the search filter repohascommitafter unusable in the presence of an empty repository. #5149
  • An issue where externalURL not being configured in the management console could go unnoticed. #3899
  • Listing branches and refs now falls back to a fast path if there are a large number of branches. Previously we would time out. #4581
  • Sourcegraph will now ignore the ambiguous ref HEAD if a repository contains it. #5291




  • Sourcegraph cluster deployments now run a more stable syntax highlighting server which can self-recover from rarer failure cases such as getting stuck at high CPU usage when highlighting some specific files. #5406 This will be ported to single-container deployments at a later date.



  • Add nameTransformations setting to GitLab external service to help transform repository name that shows up in the Sourcegraph UI.
