     *
     * The \a displayName argument must specify a translated, user-friendly name for the filter.
     *
     * The \a prefix argument specifies the prefix character(s) for this filter. Prefixing a search
     * with these characters will restrict the locator search to only include results from this filter.
     * The \a prefix must consist of at least three characters.
     *
     * The \a geocoder must specify an instance of a class which implements the QgsGeocoderInterface
     * interface. Ownership of \a geocoder is not transferred, and the caller must ensure that \a geocoder
     * exists for the lifetime of this filter.
     *
     * The \a boundingBox argument specifies the geographic bounding box, in WGS84, covered by the
     * filter.
