Search one or more string in all node in workflow

Hi everyone, I have all my wkfs saved as .zip files in a folder, I wanted to know if it was possible to do a search for one or more strings within the nodes of all the wkfs.

For example in all wkfs I should search for ‘table_name’-20-‘20’

According to you, is it possible I also have the possibility of having the wkfs unzipped
