Not sure how to do a search

Hi everyone… I’m a total beginner and need some help with a search function. Most of the info is going into the app from the user’s side and I need to be able to search for the fields that contain a certain type (AO1 or AO2 used here as an example) 1A 1B 1C are entered by the user and are not the fields name on the database. I need to search and find all the field names that, for example contain all the AO1 types inputted into the field via auto binding.
I hope I have stated this well

TIA
