3 The search API allows to look up a location from a textual description.
4 Nominatim supports structured as well as 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 tranlated into specific OpenStreetMap(OSM) tags (e.g. Pub => amenity=pub).
9 Note that this only limits the items to be found. It is not suited to return complete
10 lists of OSM objects of a specific type.
11 Use [Overpass API](https://overpass-api.de/) for that.
15 The search API has the following two formats:
18 https://nominatim.openstreetmap.org/search/<query>?<params>
21 This format only accepts a free-form query string where the
22 parts of the query are separated by slashes.
25 https://nominatim.openstreetmap.org/search?<params>
28 In this form, the query may be given through two different sets of parameters:
32 Free-form query string to search for.
33 Free-form queries are processed first left to right and then right to
34 left if that fails. So you may search for
35 [pilkington avenue, birmingham](//nominatim.openstreetmap.org/search?q=pilkington+avenue,birmingham) as well as for
36 [birmingham, pilkington avenue](//nominatim.openstreetmap.org/search?q=birmingham,+pilkington+avenue).
37 Commas are optional, but improve performance by reducing the complexity
41 * `street=<housenumber> <streetname>`
46 `postalcode=<postalcode>`
48 Alternative query string format for structured requests.
49 Structured requests are faster but are less robust against alternative
50 OSM tagging schemas. **Do not combine with** `q=<query>` **parameter**.
52 All three query forms accept the additional paramters listed below.
56 * `format=[html|xml|json|jsonv2|geojson|geocodejson]`
58 See [Place Output Formats](Output.md) for details on each format. (Default: html)
60 * `json_callback=<string>`
62 Wrap json output in a callback function (JSONP) i.e. `<string>(<json>)`.
63 Only has an effect for JSON output formats.
67 * `addressdetails=[0|1]`
69 Include a breakdown of the address into elements. (Default: 0)
74 Include additional information in the result if available,
75 e.g. wikipedia link, opening hours. (Default: 0)
80 Include a list of alternative names in the results. These may include
81 language variants, references, operator and brand. (Default: 0)
84 ### Language of results
86 * `accept-language=<browser language string>`
88 Preferred language order for showing search results, overrides the value
89 specified in the "Accept-Language" HTTP header.
90 Either use a standard RFC2616 accept-language string or a simple
91 comma-separated list of language codes.
95 * `countrycodes=<countrycode>[,<countrycode>][,<countrycode>]...`
97 Limit search results to one or more countries. `<countrycode>` must be the
98 ISO 3166-1alpha2 code, e.g. `gb` for the United Kingdom, `de` for Germany.
101 * `exclude_place_ids=<place_id,[place_id],[place_id]`
103 If you do not want certain OSM objects to appear in the search
104 result, give a comma separated list of the `place_id`s you want to skip.
105 This can be used to broaden search results. For example, if a previous
106 query only returned a few results, then including those here would cause
107 the search to return other, less accurate, matches (if possible).
112 Limit the number of returned results. (Default: 10)
115 * `viewbox=<x1>,<y1>,<x2>,<y2>`
117 The preferred area to find search results. Any two corner points of the box
118 are accepted in any order as long as they span a real box.
123 When a viewbox is given, restrict the result to items contained with that
124 viewbox (see above). When `viewbox` and `bounded` are given, an amenity
125 only search is allowed. In this case, give the special keyword for the
126 amenity in squaer brackets, e.g. `[pub]`. (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 Simplify the output geometry before returning. 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 in 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)
164 Output assorted developer debug information. Data on internals of Nominatim's
165 "Search Loop" logic, and SQL queries. The output is (rough) HTML format.
166 This overrides the specified machine readable format. (Default: 0)
