+* `json_callback=<string>`
+
+ * Wrap json output in a callback function (JSONP) i.e. `<string>(<json>)`
+
+* `accept-language=<browser language string>`

+
+## Search
+Nominatim indexes named (or numbered) features with the OSM data set and a subset of other unnamed features (pubs, hotels, churches, etc)
+
+Search terms are processed first left to right and then right to left if that fails.
+
+Both searches will work: [pilkington avenue, birmingham](//nominatim.openstreetmap.org/search?q=pilkington+avenue,birmingham), [birmingham, pilkington avenue](//nominatim.openstreetmap.org/search?q=birmingham,+pilkington+avenue)
+
+(Commas are optional, but improve performance by reducing the complexity of the search.)
+
+Where house numbers have been defined for an area they should be used: [135 pilkington avenue, birmingham](//nominatim.openstreetmap.org/search?q=135+pilkington+avenue,+birmingham)
+
+### Special Keywords
+Various keywords are translated into searches for specific osm tags (e.g. Pub => amenity=pub). A current list of [special phrases](https://wiki.openstreetmap.org/wiki/Nominatim/Special_Phrases) processed is available.
+
+### Parameters
+
+```
+ https://nominatim.openstreetmap.org/search?<params>
+ https://nominatim.openstreetmap.org/search/<query>?<params>
+```
+
+* `format=[html|xml|json|jsonv2]`
+
+ * Output format
+ * defaults to `html`
+
+
+* `json_callback=<string>`
+
+ * Wrap json output in a callback function (JSONP) i.e. `<string>(<json>)`
+
+* `accept-language=<browser language string>`
+
+ * Preferred language order for showing search results, overrides the value specified in the "Accept-Language" HTTP header.
+ * Either uses standard rfc2616 accept-language string or a simple comma separated list of language codes.
+
+* `q=<query>`
+
+ * Query string to search for.
+ * Alternatively can be entered as:
+
+ * `street=<housenumber> <streetname>`
+ * `city=<city>`
+ * `county=<county>`
+ * `state=<state>`
+ * `country=<country>`
+ * `postalcode=<postalcode>`
+
+ **(experimental)** Alternative query string format for structured requests.
+Structured requests are faster and require fewer server resources. **Do not combine with `q=<query>` parameter**.
+
+* `countrycodes=<countrycode>[,<countrycode>][,<countrycode>]...`
+
+ * Limit search results to a specific country (or a list of countries).
+ * `<countrycode>` should be the ISO 3166-1alpha2 code, e.g. `gb` for the United Kingdom, `de` for Germany, etc.
+
+* `viewbox=<x1>,<y1>,<x2>,<y2>`
+ * The preferred area to find search results. Any two corner points of the box are accepted in any order as long as they span a real box.
+
+* `bounded=[0|1]`
+ * defaults to 0
+ * Restrict the results to only items contained with the viewbox (see above).
+ * Restricting the results to the bounding box also enables searching by amenity only.
+ * For example a search query of just `"[pub]"` would normally be rejected but with `bounded=1` will result in a list of items matching within the bounding box.
+
+* `polygon=[0|1]`
+ * defaults to 0
+ * Output polygon outlines for items found **(deprecated, use one of the polygon_* parameters instead)**
+
+* `addressdetails=[0|1]`
+ * defaults to 0
+ * Include a breakdown of the address into elements
+
+* `email=<valid email address>`
+
+ * If you are making large numbers of request please include a valid email address or alternatively include your email address as part of the User-Agent string.
+ * This information will be kept confidential and only used to contact you in the event of a problem, see [Usage Policy](https://operations.osmfoundation.org/policies/nominatim/) for more details.
+
+* `exclude_place_ids=<place_id,[place_id],[place_id]`
+
+ * If you do not want certain openstreetmap 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 broaden 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)
+
+* `limit=<integer>`
+ * defaults to 10
+ * Limit the number of returned results.
+
+* `dedupe=[0|1]`
+ * defaults to 1
+ * Sometimes you have several objects in OSM identifying the same place or object in reality. The simplest case is a street being split in many different OSM ways due to different characteristics.
+ * Nominatim will attempt to detect such duplicates and only return one match; this is controlled by the dedupe parameter which defaults to 1. Since the limit is, for reasons of efficiency, enforced before and not after de-duplicating, it is possible that de-duplicating leaves you with less results than requested.
+
+* `debug=[0|1]`
+ * defaults to 0
+ * Output assorted developer debug information. Data on internals of nominatim "Search Loop" logic, and SQL queries. The output is (rough) HTML format. This overrides the specified machine readable format.
+
+* `polygon_geojson=1`
+ * Output geometry of results in geojson format.
+
+* `polygon_kml=1`
+ * Output geometry of results in kml format.
+
+* `polygon_svg=1`
+ * Output geometry of results in svg format.
+
+* `polygon_text=1`
+ * Output geometry of results as a WKT.
+
+* `extratags=1`
+ * Include additional information in the result if available, e.g. wikipedia link, opening hours.
+
+* `namedetails=1`
+ * Include a list of alternative names in the results.
+ * These may include language variants, references, operator and brand.
