# Advanced Search Syntax **(STARTER)**
|
|
|
|
> - Introduced in [GitLab Enterprise Starter](https://about.gitlab.com/pricing/) 9.2
|
|
|
|
NOTE: **GitLab.com availability:**
|
|
Advanced Search (powered by Elasticsearch) is enabled for Bronze and above on GitLab.com since 2020-07-10.
|
|
|
|
Use advanced queries for more targeted search results.
|
|
|
|
This is the user documentation. To install and configure Elasticsearch,
|
|
visit the [administrator documentation](../../integration/elasticsearch.md).
|
|
|
|
## Overview
|
|
|
|
The Advanced Search Syntax is a subset of the
|
|
[Advanced Search](advanced_global_search.md), which you can use if you
|
|
want to have more specific search results.
|
|
|
|
Advanced Search only supports searching the [default branch](../project/repository/branches/index.md#default-branch).
|
|
|
|
## Use cases
|
|
|
|
Let's say for example that the product you develop relies on the code of another
|
|
product that's hosted under some other group.
|
|
|
|
Since under your GitLab instance there are hosted hundreds of different projects,
|
|
you need the search results to be as efficient as possible. You have a feeling
|
|
of what you want to find (e.g., a function name), but at the same you're also
|
|
not so sure.
|
|
|
|
In that case, using the advanced search syntax in your query will yield much
|
|
better results.
|
|
|
|
## Using the Advanced Search Syntax
|
|
|
|
The Advanced Search Syntax supports fuzzy or exact search queries with prefixes,
|
|
boolean operators, and much more.
|
|
|
|
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?utf8=%E2%9C%93&snippets=&scope=issues&repository_ref=&search=display+bug&group_id=9970&project_id=278964) and [`bug display`](https://gitlab.com/search?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&snippets=&scope=blobs&repository_ref=&search=argument+%5C-last&group_id=9970&project_id=278964)
|
|
|
|
### Syntax search filters
|
|
|
|
The Advanced Search Syntax 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. A keyword or an asterisk (`*`) is required for filter searches and has to be added in front of the filter separated by a space.
|
|
|
|
Examples:
|
|
|
|
- Finding a file with any content named `search_results.rb`: [`* filename:search_results.rb`](https://gitlab.com/search?utf8=%E2%9C%93&snippets=&scope=blobs&repository_ref=&search=*+filename%3Asearch_results.rb&group_id=9970&project_id=278964)
|
|
- 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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&snippets=&scope=blobs&repository_ref=&search=EpicLinks+extension%3Arb&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?utf8=%E2%9C%93&snippets=&scope=blobs&repository_ref=&search=Sidekiq+path%3Aelastic&group_id=9970&project_id=278964)
|
|
- Finding the files represented by the Git object ID `998707b421c89bd9a3063333f9f728ef3e43d101`: [`* blob:998707b421c89bd9a3063333f9f728ef3e43d101`](https://gitlab.com/search?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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 Starter 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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&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?utf8=%E2%9C%93&snippets=&scope=blobs&repository_ref=&search=docs+-path%3Adocs%2F&group_id=9970&project_id=278964)
