I've tried the In function but it doesnt allow me to search anything. For exmaple with this SortByColumns(Filter([@'Issue tracker'],StartsWith('Issue description', TextSearchBox1.Text)), "Title", If(SortDescending1, SortOrder.Descending, SortOrder.Ascending)) it shows the following

When I try the In function SortByColumns(Filter([@'Issue tracker'],In('Issue description', TextSearchBox1.Text)), "Title", If(SortDescending1, SortOrder.Descending, SortOrder.Ascending)) it shows the following the inputs disappear and gives me an error
