Vallidate exposed filters in View I created a view with Search API.Could you please help how to validate exposed filter(Textbox)
with in a view.

I tried using contextual filter it never worked.
I would alter the exposed form and add a validation handler.

If I remember correctly, the form ID is views_exposed_form. Just do a check on the view object (which I think is in the $form_state variable) to only add the handler to a certain view/view display.
