+#### NOMINATIM_UPDATE_FORWARD_DEPENDENCIES
+
+| Summary | |
+| -------------- | --------------------------------------------------- |
+| **Description:** | Forward geometry changes to dependet objects |
+| **Format:** | bool |
+| **Default:** | no |
+| **Comment:** | EXPERT ONLY. Must not be enabled after import. |
+
+The geometry of OSM ways and relations may change when a node that is part
+of the object is moved around. These changes are not propagated per default.
+The geometry of ways/relations is only updated the next time that the object
+itself is touched. When enabling this option, then dependent objects will
+be marked for update when one of its member objects changes.
+
+Enabling this option may slow down updates significantly.
+
+!!! warning
+ If you want to enable this option, it must be set already on import.
+ Do not enable this option on an existing database that was imported with
+ NOMINATIM_UPDATE_FORWARD_DEPENDENCIES=no.
+ Updates will become unusably slow.
