Query Analytics Dashboard: Search by query substring or dimension

The problem: 

We  need an additional Search filter for the full-text search against  "Dimension" (Query, Server  name, Use, etc  )

UX: 

Use cases: 

• as a PMM User, I need to be able to search by QueryID so that I can easily find query I was working before and saved it's ID 
• As a PMM User, I need to be able to search by part of Query fingerprint or Service Name or other dimensions together with applied filters so that I can narrow my search in QAN 

DoD

• In addition to selected filters user can search by part of the text in value of Dimension selected for presentation in QAN 
• User can enter part of Query ID  key when they looking into Query dimension view 

Out Of Scope

•   nice error / "404 message" with suggestions to remove some filters or etc. 

 

DOC:

• Updates screens for QAN 
• the feature mentioned in ou rQAN documentation 

----------------

In PMM v1 we had ability to search by query abstract substring, like described in the doc here: https://www.percona.com/doc/percona-monitoring-and-management/qan.html

 

In PMM v2 there is no such search bar, and I do not see any ability to filter queries based on some substring / query pattern. PMM v2 documentation still says it's possible to do this: https://www.percona.com/doc/percona-monitoring-and-management/2.x/qan-filtering.html On screenshot there is "Search by Query Abstract, Fingerprint or ID" 

 

Was this search field removed intentionally, or this is some bug? This was very useful thing and I can't believe it was removed
