+The featureType allows to have a more fine-grained selection for places
+from the address layer. Results can be restricted to places that make up
+the 'state', 'country' or 'city' part of an address. A featureType of
+settlement selects any human inhabited feature from 'state' down to
+'neighbourhood'.
+
+When featureType ist set, then results are automatically restricted
+to the address layer (see above).
+
+!!! tip
+ Instead of using the featureType filters `country`, `state` or `city`,
+ you can also use a structured query without the finer-grained parameters
+ amenity or street.
+
+| Parameter | Value | Default |
+|-----------| ----- | ------- |
+| exclude_place_ids | comma-separeted 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.
+This can be used to retrieve additional search results. For example, if a
+previous query only returned a few results, then including those here would
+cause the search to return other, less accurate, matches (if possible).
+
+| Parameter | Value | Default |
+|-----------| ----- | ------- |
+| viewbox | `<x1>,<y1>,<x2>,<y2>` | _unset_ |
+
+Boost parameter which focuses the search on the given area.
+Any two corner points of the box are accepted as long as they make a proper
+box. `x` is longitude, `y` is latitude.
+
+| Parameter | Value | Default |
+|-----------| ----- | ------- |
+| 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.
+
+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
+brackets, e.g. `[pub]` and a selection of objects of this type is returned.
+There is no guarantee that the result returns all objects in the area.
