SERP: List tagged files

[tbsbdr]

Terminology: SERP = Search Engine Result Page

User Story

• As a user I want to see a list of all files with a specific tag so that I can find files regardless of their space, filename or path.

Value

• find related files regardless of their location or file name.

Acceptance Criteria

• Click on a Tag in the Fileslist or in the Details view, shows a search result page (SERP)
• The SERP lists all files that have the associated tag, ex. "gravity"
• The searchfield shows the corresponding syntax like ex. "tag:gravity"
• The SERP can get sorted (tag column can be sorted by amount of tags)
• search: syntax like "tag:gravity" in the file search lists all files with the tag "gravity" in the SERP

Automated tests

Unittests:

• none

E2E Tests

• continue E2E Test from Create tags #7135 in the following way: assign the same tag to second file, click on the tag, validate that the SERP is being rendered, validate, that the SERP contains the 2 files mentioned in the steps before.

Definition of ready

• everybody needs to understand the value written in the user story
• acceptance criteria has to be defined
• all dependencies of the user story need to be identified
• feature should be seen from an end user perspective
• user story has to be estimated
• story points need to be less then 20

Definition of done

• Functional requirements
• functionality described in the user story works
• acceptance criteria are fulfilled
• Quality
• codre review happened
• CI is green
• critical code received unit tests by the developer
• automated tests passed (if automated tests are not available, this test needs to be created and passed
• Non-functional requirements
• no sonar cloud issues

Note on terminology:
"File" is always meant as "file and folder".
