What is the language behind the regular expression usage in SMAT. I am looking to see if I can search in SMAT for messages that have ‘&’ in other locations besides directly after MSH in MSH:2. I am able to do this in other tools but though it would be nice to apply it in SMAT directly. I understand I will probably get a lot of hits if there are many messages with the ‘&’ character in fields as part of the HL7 convention. But lets say I want to find messages where the ‘&’ falls between 2 pipes or 2 carats or a combination of pipe and carat.
Example |History & Physical|^R&D|^Bob & Bill^|
Can this be done using the SMAT regular expression location?
