| **Description:** | Tokenizer used for normalizing and parsing queries and names |
| **Format:** | string |
-| **Default:** | legacy |
+| **Default:** | icu |

-#### 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.

#### NOMINATIM_LANGUAGES
| Summary | |
| **Format:** | boolean |
| **Default:** | no |
| **After Changes:** | run `nominatim refresh --website` |
+| **Comment:** | PHP frontend only |
+
This feature is currently undocumented and potentially broken.
| **Format:** | integer |
| **Default:** | 500 |
| **After Changes:** | run `nominatim refresh --website` |
+| **Comment:** | PHP frontend only |
This setting defines the threshold over which a name is no longer considered
as rare. When searching for places with rare names, only the name is used
Setting this parameter to 0 disables polygon output completely.

+
+| Summary | |
+| -------------- | --------------------------------------------------- |
+| **Description:** | Disable search for elements that are not in the country grid |
+| **Format:** | boolean |
+| **Default:** | no |
+| **After Changes:** | run `nominatim refresh --website` |
+| **Comment:** | PHP frontend only |
+
+Enable to search elements just within countries.
+
+When enabled, if, despite not finding a point within the static grid of countries, it
+finds a geometry of a region, do not return the geometry.
+Return "Unable to geocode" instead.

+| -------------- | --------------------------------------------------- |
+| **Description:** | Enable serving via URLs with a .php suffix |
+| **Format:** | boolean |
+| **Default:** | yes |
+| **Comment:** | Python frontend only |
+
+When enabled, then endpoints are reachable as `/<name>` as well as `/<name>.php`.
+This can be useful when you want to be backwards-compatible with previous
+versions of Nominatim.

+
+#### NOMINATIM_API_POOL_SIZE
+
+| Summary | |
+| -------------- | --------------------------------------------------- |
+| **Description:** | Number of parallel database connections per worker |
+| **Format:** | number |
+| **Default:** | 10 |
+| **Comment:** | Python frontend only |
+
+Sets the maximum number of database connections available for a single instance
+of Nominatim. When configuring the maximum number of connections that your
+PostgreSQL database can handle, you need at least
+`NOMINATIM_API_POOL_SIZE` * `<number of configured workers>` connections.
+For configuring the number of workers, refer to the section about
+[Deploying the Python frontend](../admin/Deployment-Python.md).
+
+#### NOMINATIM_QUERY_TIMEOUT
+
+| Summary | |
+| -------------- | --------------------------------------------------- |
+| **Description:** | Timeout for SQL queries to the database |
+| **Format:** | number (seconds) |
+| **Default:** | 10 |
+| **Comment:** | Python frontend only |
+
+When this timeout is set, then all SQL queries that run longer than the
+specified numbers of seconds will be cancelled and the user receives a
+timeout exceptions. Users of the API see a 503 HTTP error.
+
+The timeout does ont apply when using the
+[low-level DB access](../library/Low-Level-DB-Access.md)
+of the library. A timeout can be manually set, if required.

+| -------------- | --------------------------------------------------- |
+| **Description:** | Timeout for search queries |
+| **Format:** | number (seconds) |
+| **Default:** | 60 |
+| **Comment:** | Python frontend only |
+
+When this timeout is set, a search query will finish sending queries
+to the database after the timeout has passed and immediately return the
+results gathered so far.
+
+Note that under high load you may observe that users receive different results
+than usual without seeing an error. This may cause some confusion.

### Logging Settings
#### NOMINATIM_LOG_DB
type contains the name of the endpoint used.
Can be used as the same time as NOMINATIM_LOG_DB.
+
+#### NOMINATIM_DEBUG_SQL
+
+| Summary | |
+| -------------- | --------------------------------------------------- |
+| **Description:** | Enable printing of raw SQL by SQLAlchemy |
+| **Format:** | boolean |
+| **Default:** | no |
+| **Comment:** | **For developers only.** |
+
+This settings enables
+[SQL debugging](https://docs.sqlalchemy.org/en/20/core/engines.html#dbengine-logging)
+by SQLAlchemy. This can be helpful when debugging some bugs with internal
+query handling. It should only be used together with the CLI query functions.
+Enabling it for server mode may have unintended consequences. Use the `debug`
+parameter instead, which prints information on how the search is executed
+including SQL statements.
