Nominatim has a nice feature to provide an icon URL for search results, for example a shop icon if you search for supermarkets. I use these icons now for the search result markers on my map (http://osm.cdauth.de/map/). Although I don’t know if I will not restore the old marker icons, because these new icons aren’t very prominent on the map.

Undocumented feature time. Replace .p. with .n. for a stronger icon.
replace .20. with .12., .16., etc. for a different size. Full icon set here:
