I want to search for the title in a tip macro (i.e., "This is the title" in {tip:title=This is the title}), but Confluence doesn't allow this.

There are many tickets about this issue, but they have been closed or doesn't solve the problem.

I want to know your interest in this issue. Do you think I should open a new ticket on this issues?
I think this issue could be solved if we could search for the source code of pages, but this also seems not possible.
