Yes, but it depends on what you want to parse with that regex. If you want to parse exactly the string "de.c++issues", then you need the regex `de\.c\+\+issues`. Note that I also escaped the '.' as that is a special char in regexes as well. (Escaping is the method of removing the specialness of special characters by putting a '\' in front of them) Or as salva propossed, you could write `\Qde.c++issues\E`, that would automatically escape all special characters between \Q and \E. This is probably the better way as you don't seem to know much abouts regexes and there are a lot more special characters	[reply] [d/l] [select]
