Setup QGIS Display name to return only unique values from a search

In QGIS I am trying to setup the Locator to return matching Street Entry from the attribute table as opposed to all matching without creating a new merged layer. In the Display Expression I tried using the collect function as follows

 collect($geometry,"STREET_NM")

As well as a few variations of this including collect_geometries and line_merge. If I do the search as just STREET_NM every line segment with that street name is returned; I only want 1 return and the geometry to be all the line segments matching that return. Is there an Expression that can perform this function?
