# Search

## Search OSM features by name

`search.query(**kwargs) -> FeatureCollection`

**get** `/api/v1/search`

Search OSM features by name

### Parameters

- `q: String`

  Search query string

- `cursor: String`

  Cursor for pagination

- `limit: Integer`

  Maximum results (default 25, max 100)

- `output_fields: String`

  Comma-separated property fields to include

- `output_include: String`

  Extra computed fields: bbox, distance, center

- `output_precision: Integer`

  Coordinate decimal precision (1-15, default 7)

- `output_sort: String`

  Sort by: distance, name, osm_id

### Returns

- `class FeatureCollection`

  GeoJSON FeatureCollection (RFC 7946). For paginated endpoints, metadata is returned in HTTP response headers rather than the body:

| Header          | Description                                      |
| --------------- | ------------------------------------------------ |
| `X-Limit`       | Requested result limit                           |
| `X-Has-More`    | `true` if more results exist                     |
| `X-Next-Cursor` | Opaque cursor for next page (cursor pagination)  |
| `X-Next-Offset` | Numeric offset for next page (offset pagination) |
| `Link`          | RFC 8288 `rel="next"` link to the next page      |

  Content-Type is `application/geo+json`.

  - `features: Array[GeoJsonFeature]`

    Array of GeoJSON Feature objects

    - `geometry: GeoJsonGeometry`

      GeoJSON Geometry object per RFC 7946. Coordinates use [longitude, latitude] order. 3D coordinates [lng, lat, elevation] are used for elevation endpoints.

      - `coordinates: Array[Float] | Array[Array[Float]] | Array[Array[Array[Float]]] | Array[Array[Array[Array[Float]]]]`

        Coordinates array. Nesting depth varies by geometry type: Point = [lng, lat], LineString = [[lng, lat], ...], Polygon = [[[lng, lat], ...], ...], etc.

        - `Array[Float]`

          [longitude, latitude] or [longitude, latitude, elevation]

        - `Array[Array[Float]]`

          Array of [lng, lat] positions

        - `Array[Array[Array[Float]]]`

          Array of linear rings / line strings

        - `Array[Array[Array[Array[Float]]]]`

          Array of polygons

      - `type: :Point | :LineString | :Polygon | 3 more`

        Geometry type

        - `:Point`

        - `:LineString`

        - `:Polygon`

        - `:MultiPoint`

        - `:MultiLineString`

        - `:MultiPolygon`

    - `properties: Hash[Symbol, untyped]`

      OSM tags flattened as key-value pairs, plus `@type` (node/way/relation) and `@id` (OSM ID) metadata fields. May include `distance_m` for proximity queries.

    - `type: :Feature`

      Always `Feature`

      - `:Feature`

    - `id: String`

      Compound identifier in `type/osm_id` format

  - `type: :FeatureCollection`

    Always `FeatureCollection`

    - `:FeatureCollection`

### Example

```ruby
require "plaza"

plaza = Plaza::Client.new(
  api_key: "My API Key",
  environment: "local" # defaults to "production"
)

feature_collection = plaza.search.query(q: "q")

puts(feature_collection)
```

#### Response

```json

  "features": [
    {
      "geometry": {
        "coordinates": [
          2.3522,
