+| 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.

#### NOMINATIM_IMPORT_STYLE
| **Default:** | extratags |

+You can also write your own custom style and point the setting to the file
+with the style. When a relative path is given, then the style file is searched
+first relative to the project directory and then in the global settings

### Logging Settings

+file where to log to. A relative file name is assumed to be relative to
+the project directory.
+
+
+The entries in the log file have the following format:
<request time> <execution time in s> <number of results> <type> "<query string>"
Request time is the time when the request was started. The execution time is
-given in ms and corresponds to the time the query took executing in PHP.
