Escaped \+ not working when used along with |?

[tapyu]

Summary

I apologize if that is a typo on my side, but it seems that the scaped \+does not work when it is used with |.

Reproduction Steps

Consider the following text and the following select regex pattern

It should match C and C++, shouldn't???

On the other hand, for some reason, we can get this done if we swap the regex matches:

I'm pretty sure it's because C gets matched before C++ in the first example. C\b|C\+\+ would work for example.

I didn't work either, but I think you find the "issue". That behavior is the same as other Regex's matching in other software. Therefore that is not a helix bug.

its simply a matter of ordering alternations correctly, C|C\+\+ does work.

I think C\+\+|C is probably what Pascal meant

ah right sory I copied the wrong thing
