How to get the list of tickets commented by "User A" with the text "Validation"

I want to write a query which should list the tickets with 2 conditions 

1. User <User A>

2. search in the comments to see this keyword "Validation"

help on this is much appreciated.

OOTB you cannot search for comment by a specific user. You will need an addon for that. You can search for all comments with “validation” as follows

comment ~ “validation”
