-Filer that limits the search results to one or more countries.
+Filter that limits the search results to one or more countries.
The country code must be the
[ISO 3166-1alpha2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) code
of the country, e.g. `gb` for the United Kingdom, `de` for Germany.
This parameter should not be confused with the 'country' parameter of
the structured query. The 'country' parameter contains a search term
and will be handled with some fuzziness. The `countrycodes` parameter
- is a hard filter and as such should be prefered. Having both parameters
+ is a hard filter and as such should be preferred. Having both parameters
in the same query will work. If the parameters contradict each other,
the search will come up empty.

+The layer filter allows to select places by themes.
The `address` layer contains all places that make up an address:
address points with house numbers, streets, inhabited places (suburbs, villages,

features are imported into the database.

+| exclude_place_ids | comma-separated list of place ids |
If you do not want certain OSM objects to appear in the search
result, give a comma separated list of the `place_id`s you want to skip.
| bounded | 0 or 1 | 0 |
When set to 1, then it turns the 'viewbox' parameter (see above) into
-a filter paramter, excluding any results outside the viewbox.
+a filter parameter, excluding any results outside the viewbox.
When `bounded=1` is given and the viewbox is small enough, then an amenity-only
search is allowed. Give the special keyword for the amenity in square

of the output geometry. The parameter describes the
tolerance in degrees with which the geometry may differ from the original
geometry. Topology is preserved in the geometry.
