Using Input Fields (multiple lines) property control to filter

Someone had posted about this topic originally but a link they posted in the original post was broken (

I'm essentially trying to do the same thing that the OP of the  linked post was doing. I have a list of unique IDs that I'd like to be able to paste into a text box that will filter down my selection by those unique IDs. Can someone let me know what the easiest way to do this would be using the property control (Input Fields {multiple lines})?
