I had great success with searching through a loaded file. I'm going to stop researching the problem and consider the issue solved. If anyone is curious of what worked:
(1) load entire json file into a global variable(data) at layout start
(2) added delimiters to start and end of searchable text
(3) query the data using "test regex" condition
*** after using this method the animation stop until search completed no longer happens (or at least not noticeable on my test devices) ***
