I guess this is a feature request, since I can't seem to find way to accomplish it with X1 v 5.2 and I feel it's pretty critical.
I'd like to be able search for text in the middle of a string. For example, If someone's email address is donjohnson12@notreal.com and I want to find the emails he's sent me but all I can remember is that his email address has 'johnson' in it... I think X1 should be able to find it. Currently X1 can't seem to search for text in the middle of strings, however this kind of functionality is really important.
I'd suggest using a meta-character (like *) in front of the search text to denote that zero or more characters before the search text is ok. Example: searching for *johnson would find:
johnsoncakes@fake_email.com
donjohnson12@notreal.com
mary.johnson@bogus.org etc...
Any chance that this is something X1 could add?
