Search inside files on remote server (mac)?

Question

macOS

Hello!
I dug through all the Ftp managers under mac, but did not find one that had a normal search inside the files on the server. There are options simply with a search by name and the like, but these "subhumans" do not search inside the files.
I was looking for a variant of plugins for Finder (and analogues), so that they could search inside the files, but still the result is the same. =(
Or if there are no options to solve the problem through the FTP client, then can you tell me how you solve this problem?
Help me solve the problem ....
Thank you!
