+`osmtype` and `osmid` are required parameter. The type is one of node (N), way (W)
+or relation (R). The id must be a number. The `class` parameter is optional and
+allows to distinguish between entries, when the corresponding OSM object has more
+than one main tag. For example, when a place is tagged with `tourism=hotel` and
+`amenity=restaurant`, there will be two place entries in Nominatim, one for a
+restaurant, one for a hotel. You need to specify `class=tourism` or `class=amentity`
+to get exactly the one you want. If there are multiple places in the database
+but the `class` parameter is left out, then one of the places will be chosen
+at random and displayed.

-The placeid created assigned sequentially during Nominatim data import. It is different between servers and changes when data gets reimported. Therefore it can't be used as permanent id and shouldn't be used in bug reports.
