+## Advanced Search syntax
 
-Elasticsearch has data for the default branch only. 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 is 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 shows
-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 - for example: 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) 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 (`*`) is 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)

+# Advanced Search syntax **(PREMIUM)**
+
+With [Advanced Search](../advanced_search.md), you can perform a thorough
+search through your entire GitLab instance.
+
+The Advanced Search syntax supports fuzzy or exact search queries with prefixes,
+boolean operators, and much more. Advanced Search uses
+[Elasticsearch's syntax](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-simple-query-string-query.html#simple-query-string-syntax).
+
+WARNING:
+Advanced Search searches projects' default branches only.
+
+See query examples on the tables below and their respective expected output.
+The examples link to a search on GitLab.com to help you visualize the output.
+
+## General search

+| Query example | Expected output |
+|---|---|
+[`“display bug”`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=%22display+bug%22&group_id=9970&project_id=278964) | Returns the **exact phrase** _display bug_ (stemming still applies). |
+[`bug -display`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+-display&group_id=9970&project_id=278964) | Results include _bug_, and **exclude** _display_. |
+[`bug \| display`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+display+%7C+banner&group_id=9970&project_id=278964) | Results include _bug_ **or** _display_. |

+| [`bug error 50*`](https://gitlab.com/search?snippets=&scope=issues&repository_ref=&search=bug+error+50*&group_id=9970&project_id=278964) | `*` finds **partial matches**. Results include _bug_, _error_, and the partial _50_ (looking for any 500 errors, for example). |
+| [`bug \-display`](https://gitlab.com/search?snippets=&scope=blobs&repository_ref=&search=argument+%5C-last&group_id=9970&project_id=278964) | `\` **scapes symbols**. Results include _bug_ **and** _-display_. |
