Seach for String containing - wildcard search

Hi

I have in my AirTable a list of Names. Lets say I want to find all results with last name "brown". I am making a search for people with formular like this:

filterByFormula: LOWER({TABLE_ID})="brown"

How can I do it that if I search "bro", or even "own", it will also send the result of someone with name "brown". Meaning I want to receive when the String contains the seach word, not just when its an exact match.

Thanks
