GREP style doesn't work, Find/Change GREP does

[mosgoruser]

I have a paragraph style with a GREP style inside that renders the first three words after the name (first paragraph) in small caps:

(?<=\r~h)\w+\s\w+\s\w+

The “name” grep style also doesn't work btw, but let me focus on “small caps” for now. The thing is, the exact same Find/Change GREP query works just fine and returns exactly what I'm looking for. However, when in a style, it doesn't seem to work at all. Moreover, I went as far as creating a new document with a text frame with placeholder text and making a paragraph style with just the GREP and nothing else to make sure I'm not missing something the stacked up during the style build-up and it had no effect. Even tried it on different versions of InDesign.

What if you try \r~h\K instead of (?<=\r~h) ?

GREP styles cannot look "outside" of the single paragraph that they are defined "in". That means, in practice, you cannot use anything with "\r".

Use the common markers "^" and "$" for 'start of paragraph' and 'end of paragraph' instead. These do work in a GREP style because they do not explicitly test for presence of "\r" or its cousin "~h".

^^ Correct answer ^^

As far as I'm concerned anyway.
