title: Doing AND queries with ReactiveSearch
body: <p>Is it possible to do AND queries with Reactivesearch? It seems that if you select multiple criteria in a multidatalist, it will return records that match any one of the criteria you selected. I want to modify the search such that if I select multiple criteria, then only those records are returned that match all the criteria that I selected. </p>
  
  <p>For example, if some movies are tagged as both thriller and drama and others are tagged as either drama only or thriller only and I select both thriller and drama, then only those movies should be returned that are tagged as both thriller and drama. Movies that are tagged as only drama or only thriller should not be returned. </p>
