In order to prevent a bias towards any of the two matching engines, we are not pre-selecting any of the matching engines when starting a new search (see Fig. 1).

As a consequence of this, when you hit the "Search" button, no new search will be started. 

In order to start a search for a patient there are two options: 

• Select a matching engine and search type each time you add a patient

• Go to your preferences and select your preferred matching engine. From that moment on, that matching engine will be selected by default when adding a new patient.
