The function ScanForDuplicates has been refactored and is now much more easy to use because it does much more stuff inside to have an easier api.
"RebuildDuplicatesCache" and "ScanForDuplicates" have been refactored.
The fields used in the prefilter don't have to be configured manually by the user. Instead, the fields defined by the prefilter now get added automatically to the list of fields to be used. In the case, that the field has been added via the users config anyways, it doesn't get added by code to ensure that each field is mentioned exactly once.
To reflect these changes, the javadoc including the example of ScanForDuplicates and RebuildDuplicates has been updated.
 Until it's possible to load values from a consumed entity dynamically via code, the possibility to select entity fields from consumed entities via ui has been removed. See ticket #1044577. Now only "native" fields directly from the base entity can be selected.
 Since the entity fields are now used in the configuration of the duplicate search, no db fields have to be configured any more. The field has been removed from liquibase
