Any field included in the DataPage wizard can be made editable through Search and Report's Details Page. This means that the data of the field can be changed and submitted back into the database.
To do so, select your DataPage from the DataPages listing screen and click on Edit to open the wizard for editing the DataPage. Navigate to the Configure Details Page Fields screen. Select each of the fields that should be editable and set its form element to Text Box or any other form element that matches the field. Click Finish on the wizard and you will be able to edit those fields.
