Hi Tamika,
This is same as we use regular expression syntax anywhere for match. Here your string in Text to match property {{lisa.httpvirtuallistner.rsp}} will be compared to Criteria on the basis of compare type .
Let's have an example.
If i say Text to match property contains "Lisa" and match type is exactly equals then it will return true and navigate to respective step if and only if you have mentioned Lisa in creteria. Another way down if it is other than "Lisa" then it will return false
Similarly if you are using regular expression and suppose you have to match if incoming texttomatch string should contain Lisa anywhere in it then this should be your regular expression
Regular expression: *Lisa* (where * indicates any character before after Lisa and will match strings like abcdefLisartuiiio , hgjkkhhjkLisayuuii and so on) .
You have to build regular expression yourself according to your incoming expected string .
Hope it helps
