3 The search API allows you to look up a location from a textual description
4 or address. Nominatim supports structured and free-form search queries.
6 The search query may also contain
7 [special phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases)
8 which are translated into specific OpenStreetMap (OSM) tags (e.g. Pub => `amenity=pub`).
9 This can be used to narrow down the kind of objects to be returned.
12 Special phrases are not suitable to query all objects of a certain type in an
13 area. Nominatim will always just return a collection of the best matches. To
14 download OSM data by object type, use the [Overpass API](https://overpass-api.de/).
18 The search API has the following format:
21 https://nominatim.openstreetmap.org/search?<params>
24 The search term may be specified with two different sets of parameters:
28 Free-form query string to search for.
29 Free-form queries are processed first left-to-right and then right-to-left if that fails. So you may search for
30 [pilkington avenue, birmingham](https://nominatim.openstreetmap.org/search?q=pilkington+avenue,birmingham) as well as for
31 [birmingham, pilkington avenue](https://nominatim.openstreetmap.org/search?q=birmingham,+pilkington+avenue).
32 Commas are optional, but improve performance by reducing the complexity of the search.
35 * `street=<housenumber> <streetname>`
40 * `postalcode=<postalcode>`
42 Alternative query string format split into several parameters for structured requests.
43 Structured requests are faster but are less robust against alternative
44 OSM tagging schemas. **Do not combine with** `q=<query>` **parameter**.
46 Both query forms accept the additional parameters listed below.
50 * `format=[xml|json|jsonv2|geojson|geocodejson]`
52 See [Place Output Formats](Output.md) for details on each format. (Default: jsonv2)
54 * `json_callback=<string>`
56 Wrap JSON output in a callback function ([JSONP](https://en.wikipedia.org/wiki/JSONP)) i.e. `<string>(<json>)`.
57 Only has an effect for JSON output formats.
61 * `addressdetails=[0|1]`
63 Include a breakdown of the address into elements. (Default: 0)
68 Include additional information in the result if available,
69 e.g. wikipedia link, opening hours. (Default: 0)
74 Include a list of alternative names in the results. These may include
75 language variants, references, operator and brand. (Default: 0)
78 ### Language of results
80 * `accept-language=<browser language string>`
82 Preferred language order for showing search results, overrides the value
83 specified in the ["Accept-Language" HTTP header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Language).
84 Either use a standard RFC2616 accept-language string or a simple
85 comma-separated list of language codes.
89 * `countrycodes=<countrycode>[,<countrycode>][,<countrycode>]...`
91 Limit search results to one or more countries. `<countrycode>` must be the
92 [ISO 3166-1alpha2](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) code,
93 e.g. `gb` for the United Kingdom, `de` for Germany.
95 Each place in Nominatim is assigned to one country code based
96 on OSM country boundaries. In rare cases a place may not be in any country
97 at all, for example, in international waters.
99 * `exclude_place_ids=<place_id,[place_id],[place_id]`
101 If you do not want certain OSM objects to appear in the search
102 result, give a comma separated list of the `place_id`s you want to skip.
103 This can be used to retrieve additional search results. For example, if a
104 previous query only returned a few results, then including those here would
105 cause the search to return other, less accurate, matches (if possible).
110 Limit the number of returned results. (Default: 10, Maximum: 50)
113 * `viewbox=<x1>,<y1>,<x2>,<y2>`
115 The preferred area to find search results. Any two corner points of the box
116 are accepted as long as they span a real box. `x` is longitude,
122 When a viewbox is given, restrict the result to items contained within that
123 viewbox (see above). When `viewbox` and `bounded=1` are given, an amenity
124 only search is allowed. Give the special keyword for the amenity in square
125 brackets, e.g. `[pub]` and a selection of objects of this type is returned.
126 There is no guarantee that the result is complete. (Default: 0)
131 * `polygon_geojson=1`
136 Output geometry of results as a GeoJSON, KML, SVG or WKT. Only one of these
137 options can be used at a time. (Default: 0)
139 * `polygon_threshold=0.0`
141 Return a simplified version of the output geometry. The parameter is the
142 tolerance in degrees with which the geometry may differ from the original
143 geometry. Topology is preserved in the result. (Default: 0.0)
147 * `email=<valid email address>`
149 If you are making large numbers of request please include an appropriate email
150 address to identify your requests. See Nominatim's [Usage Policy](https://operations.osmfoundation.org/policies/nominatim/) for more details.
154 Sometimes you have several objects in OSM identifying the same place or
155 object in reality. The simplest case is a street being split into many
156 different OSM ways due to different characteristics. Nominatim will
157 attempt to detect such duplicates and only return one match unless
158 this parameter is set to 0. (Default: 1)
162 Output assorted developer debug information. Data on internals of Nominatim's
163 "Search Loop" logic, and SQL queries. The output is (rough) HTML format.
164 This overrides the specified machine readable format. (Default: 0)
