# GitLab Advanced Search **(PREMIUM)**
|
|
|
|
> - Moved to GitLab Premium in 13.9.
|
|
|
|
NOTE:
|
|
This is the user documentation. To configure the Advanced Search,
|
|
visit the [administrator documentation](../../integration/elasticsearch.md).
|
|
Advanced Search is enabled in GitLab.com.
|
|
|
|
GitLab Advanced Search expands on the Basic Search with an additional set of
|
|
features for faster, more advanced searches across the entire GitLab instance
|
|
when searching in:
|
|
|
|
- Projects
|
|
- Issues
|
|
- Merge requests
|
|
- Milestones
|
|
- Epics
|
|
- Comments
|
|
- Code
|
|
- Commits
|
|
- Wiki (except [group wikis](../project/wiki/group.md))
|
|
- Users
|
|
|
|
The Advanced Search can be useful in various scenarios:
|
|
|
|
- **Faster searches:**
|
|
Advanced Search is based on Elasticsearch, which is a purpose-built full
|
|
text search engine that can be horizontally scaled so that it can provide
|
|
search results in 1-2 seconds in most cases.
|
|
- **Code Maintenance:**
|
|
Finding all the code that needs to be updated at once across an entire
|
|
instance can save time spent maintaining code.
|
|
This is especially helpful for organizations with more than 10 active projects.
|
|
This can also help build confidence is code refactoring to identify unknown impacts.
|
|
- **Promote innersourcing:**
|
|
Your company may consist of many different developer teams each of which has
|
|
their own group where the various projects are hosted. Some of your applications
|
|
may be connected to each other, so your developers need to instantly search
|
|
throughout the GitLab instance and find the code they search for.
|
|
|
|
## Use the Advanced Search syntax
|
|
|
|
Elasticsearch has only data for the default branch. That means that if you go
|
|
to the repository tree and switch the branch from the default to something else,
|
|
then the "Code" tab in the search result page will be served by the basic
|
|
search even if Elasticsearch is enabled.
|
|
|
|
The Advanced Search syntax supports fuzzy or exact search queries with prefixes,
|
|
boolean operators, and much more. Use the search as before and GitLab will show
|
|
you matching code from each project you have access to.
|
|
|
|
|
|
|
|
Full details can be found in the [Elasticsearch documentation](https://www.elastic.co/guide/en/elasticsearch/reference/5.3/query-dsl-simple-query-string-query.html#_simple_query_string_syntax), but
|
|
here's a quick guide:
|
|
|
|
- Searches look for all the words in a query, in any order - e.g.: searching
|
|
issues for [`display bug`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=display+bug&group_id=9970&project_id=278964) and [`bug display`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+Display&group_id=9970&project_id=278964) will return the same results.
|
|
- To find the exact phrase (stemming still applies), use double quotes: [`"display bug"`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=%22display+bug%22&group_id=9970&project_id=278964)
|
|
- To find bugs not mentioning display, use `-`: [`bug -display`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+-display&group_id=9970&project_id=278964)
|
|
- To find a bug in display or banner, use `|`: [`bug display | banner`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+display+%7C+banner&group_id=9970&project_id=278964)
|
|
- To group terms together, use parentheses: [`bug | (display +banner)`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+%7C+%28display+%2Bbanner%29&group_id=9970&project_id=278964)
|
|
- To match a partial word, use `*`. In this example, I want to find bugs with any 500 errors. : [`bug error 50*`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+error+50*&group_id=9970&project_id=278964)
|
|
- To use one of symbols above literally, escape the symbol with a preceding `\`: [`argument \-last`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=argument+%5C-last&group_id=9970&project_id=278964)
|
|
|
|
## Syntax search filters
|
|
|
|
Advanced Search also supports the use of filters. The available filters are:
|
|
|
|
- `filename`: Filters by filename. You can use the glob (`*`) operator for fuzzy matching.
|
|
- `path`: Filters by path. You can use the glob (`*`) operator for fuzzy matching.
|
|
- `extension`: Filters by extension in the filename. Please write the extension without a leading dot. Exact match only.
|
|
- `blob`: Filters by Git `object ID`. Exact match only.
|
|
|
|
To use them, add them to your keyword in the format `<filter_name>:<value>` without
|
|
any spaces between the colon (`:`) and the value. When no keyword is provided, an asterisk (`*`) will be used as the keyword.
|
|
|
|
Examples:
|
|
|
|
- Finding a file with any content named `search_results.rb`: [`* filename:search_results.rb`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=*+filename%3Asearch_results.rb&group_id=9970&project_id=278964)
|
|
- The leading asterisk (`*`) can be ignored in the case above: [`filename:search_results.rb`](https://gitlab.com/search?group_id=9970&project_id=278964&scope=blobs&search=filename%3Asearch_results.rb)
|
|
- Finding a file named `found_blob_spec.rb` with the text `CHANGELOG` inside of it: [`CHANGELOG filename:found_blob_spec.rb`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=CHANGELOG+filename%3Afound_blob_spec.rb&group_id=9970&project_id=278964)
|
|
- Finding the text `EpicLinks` inside files with the `.rb` extension: [`EpicLinks extension:rb`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=EpicLinks+extension%3Arb&group_id=9970&project_id=278964)
|
|
- Finding any file with the `.yaml` extension: [`extension:yaml`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=extension%3Ayaml&group_id=9970&project_id=278964)
|
|
- Finding the text `Sidekiq` in a file, when that file is in a path that includes `elastic`: [`Sidekiq path:elastic`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=Sidekiq+path%3Aelastic&group_id=9970&project_id=278964)
|
|
- Finding any file in a path that includes `elasticsearch`: [`path:elasticsearch`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=path%3Aelasticsearch&group_id=9970&project_id=278964)
|
|
- Finding the files represented by the Git object ID `998707b421c89bd9a3063333f9f728ef3e43d101`: [`* blob:998707b421c89bd9a3063333f9f728ef3e43d101`](https://gitlab.com/search?snippets=false&scope=blobs&repository_ref=&search=*+blob%3A998707b421c89bd9a3063333f9f728ef3e43d101&group_id=9970)
|
|
- Syntax filters can be combined for complex filtering. Finding any file starting with `search` containing `eventHub` and with the `.js` extension: [`eventHub filename:search* extension:js`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=eventHub+filename%3Asearch*+extension%3Ajs&group_id=9970&project_id=278964)
|
|
|
|
### Excluding filters
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/31684) in GitLab 13.3.
|
|
|
|
Filters can be inverted to **filter out** results from the result set, by prefixing the filter name with a `-` (hyphen) character, such as:
|
|
|
|
- `-filename`
|
|
- `-path`
|
|
- `-extension`
|
|
- `-blob`
|
|
|
|
Examples:
|
|
|
|
- Finding `rails` in all files but `Gemfile.lock`: [`rails -filename:Gemfile.lock`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=rails+-filename%3AGemfile.lock&group_id=9970&project_id=278964)
|
|
- Finding `success` in all files excluding `.po|pot` files: [`success -filename:*.po*`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=success+-filename%3A*.po*&group_id=9970&project_id=278964)
|
|
- Finding `import` excluding minified JavaScript (`.min.js`) files: [`import -extension:min.js`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=import+-extension%3Amin.js&group_id=9970&project_id=278964)
|
|
- Finding `docs` for all files outside the `docs/` folder: [`docs -path:docs/`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=docs+-path%3Adocs%2F&group_id=9970&project_id=278964)
|
|
|
|
## Search by issue or merge request ID
|
|
|
|
You can search a specific issue or merge request by its ID with a special prefix.
|
|
|
|
- To search by issue ID, use prefix `#` followed by issue ID. For example, [#23456](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=%2323456&group_id=9970&project_id=278964)
|
|
- To search by merge request ID, use prefix `!` followed by merge request ID. For example [!23456](https://gitlab.com/search?snippets=&scope=merge_requests&repository_ref=&search=%2123456&group_id=9970&project_id=278964)
|
|
|
|
## Global search scopes **(FREE SELF)**
|
|
|
|
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/68640) in GitLab 14.3.
|
|
|
|
To improve the performance of your instance's global search, you can limit
|
|
the scope of the search. To do so, you can exclude global search scopes by disabling
|
|
[`ops` feature flags](../../development/feature_flags/index.md#ops-type).
|
|
|
|
Global search has all its scopes **enabled** by default in GitLab SaaS and
|
|
self-managed instances. A GitLab administrator can disable the following `ops`
|
|
feature flags to limit the scope of your instance's global search and optimize
|
|
its performance:
|
|
|
|
| Scope | Feature flag | Description |
|
|
|--|--|--|
|
|
| Code | `global_search_code_tab` | When enabled, the global search includes code as part of the search. |
|
|
| Commits | `global_search_commits_tab` | When enabled, the global search includes commits as part of the search. |
|
|
| Issues | `global_search_issues_tab` | When enabled, the global search includes issues as part of the search. |
|
|
| Merge Requests | `global_search_merge_requests_tab` | When enabled, the global search includes merge requests as part of the search. |
|
|
| Wiki | `global_search_wiki_tab` | When enabled, the global search includes wiki as part of the search. [Group wikis](../project/wiki/group.md) are not included. |
