Can I search JIRA for issues where the Reviews text matches my string

[Claire Jarosz]

I would like to query for issues in JIRA where (apart from everything else) I check for text / emptiness of the Review tab (in the Activity section).  For example,

where project = ASDF and issue type in (story, bug) and sprint in (234, 345) and Reviews is not empty

At the moment I cannot find a way to interact with the Reviews tab - is it possible?  I would settle for even a simply "is not empty" but being able to check for a specific string would be very helpful.

dont know how to search tab info, but if you want to find something that not empty - try "!= null" it means not empty.

Cheers!
