I have a key set as 'abc xyz' and the value as '123456789...' and I unable to search all crashes that have the key pair matching these values and unable to find any documentation for the same as well.
firebase console does guide me with the following text for keys but isn't showing anything how to search for values.
Add "key:" to search for keys
You should type
key:abc value:123456789
in the field with the hint 'Search issue title, subtitle or keys'.
