text: There are 3 mistakes:
  1) The search engine is missing the important feature to retrieve names that only differ in hyphens or spaces. If you want to change that, I suggest you file a ticket on https://github.com/openstreetmap/Nominatim/issues.
  2) You wrote the name in an unusual way. You should insert a space between "Altlerchenfelder" and "Kirche".
  3) The name in OSM was also spelled in an unusual way. I think I have corrected this now.
