Thanks a lot @Fox it works, but there is another problem that I have.
If I have a big file output with Page Html command from Browser Option the result there is no result, but i I try for example a small chunk of text in the file it finds the google plus link.
Also tried with a variable following this tutorial from bablosoft https://www.youtube.com/watch?v=U88xUpj2BiI but the output is not there either if I try to put it on a file or log the variable. Here is an example:
alt text
If there is little text in file then the output is this
alt text
EDIT: Somehow I made it work, thanks again
