Ok… making progress. I figured out I can get a search box using a custom template based on the data-table template.
It’s now working great showing a search box on the page except that it shows the first num=xx files by default before a search has been done. Setting to 0 or -1 just shows all files.
Is there any way to have the search field there but not show any files by default until a search term is entered and then show num=xx files in pagination?
