Filter Text no match case

I have a database with a list of products, with a “title” text field and a “category” text field The two fields have that the texts entered contain both uppercase and lowercase characters On the page with the product list I have two search text boxes, associated with the variables Everything works perfectly, except that the search string must be case sensitive. Instead, I would like the search to be complete regardless of case I have tried various solutions, but to no avail Does anyone know how to intervene with Wappler? Thank you
