How do I search for a phrase in the text?

I have 6,100 cases of a certain error type “no response”. The response string to the BitGo API call in some of thses cases has the string “InvalidAmount”.

How do I use sentry from the listing of “no response” to filter those cases with this response string “InvalidAmount”?

My efforts thus far suggest that Sentry does not/cannot search inside issues for common reported errors. Hope I am wrong.

Thank you.
