Does the TCP Monitor "Response contains" need an exact string, or is it really "contains"

This wasn't really clear in the documentation:

The scenario is on the TCP connect I was expecting it to be like the single page monitors, where I could just specify a string that it looks for inside the page.

What I am finding is I can specify a known string in the return from the TCP check and it still fails. The response from the service contains some things every time, but it receives different numbers in various places each connect so I can't watch for the whole string.

Just looking for a definitive answer to if this field should be acting as a contains, or it is really a "match".

Thanks in advance!

it seems to be an exact match , we will try to update UI text or otherwise might add an option to do contain. It would be nice if you can create an issue.

How do I go about creating an issue?
