How to search "something" in rules/scripts

Setup, Configuration and Use Beginners
1

I have a lot of scripts and rules (both in DSL and Blocky). In one of them I change the state of item, but I can’t remember in which one.

And now the right question - can I somehow find the script where I refer to this item? Is there any search engine for “phrases” inside scripts/rules?

Use the developer sidebar.
