Issue with word boundary regex

Hi, are there any known issues matching word boundaries with a \b in a regular expression?
 
I'm trying to match the word "live" using the regex \b[lL]ive\b and it seems to also be matching "alive," which I believe it shouldn't.
 
thanks
John

    Hi John,
    I just tested the \blive\b in @Voice, and all seems to work correctly. If you have a problem with a more complex match, please send me the exact RegEx expression you use, and describe the purpose, maybe then I'll be able to help.

    Hi, Greg
     
    The exact regex I was using was \b[lL]ive\b and my replacement text was "liv" the issue was that it was also matching the string "alive" are you finding that that regex does not match "alive"?
     
    thanks

    I would have to see the exact replacements you used and test them. You could export your replacements to a file and email to me as an attachment. The:
     
    \b[lL]ive\b
     
    should not match "alive", because "a" before the "live" part is not a white space, so it does not match \b delimiter.
