This thread is resolved. Here is a description of the problem and solution.
Problem:
I am trying to use the Views Query filter to check if a Date field was filled in or is blank. What is the best way to check that using the options available in the Query Filter?
Solution:
I suggest you try Views filter hook wpv_filter_query, for example, when user submit the search form, use wpv_filter_query to trigger a PHP function, in this function check the "Date field was filled in or is blank", then do what you want.
