OCMod multiline search not working anymore

I am developing an extension for Opencart 2.x and I am trying to use ocMod multi-line search.
I've tried the multi-line search and it worked fine even with 5 lines search, which was great, but for some reason now, after I made a small modification to the <add> element, it stopped working.

What I want to know is:
1- Is there a problem with ocMode multi-line search functionality?
2- Has ocMode been `abolished`? (since I seem to be the only one 'playing' with it).

Thank you.
