Handling the entity search response

When you send a request to Entity Search API, it returns a SearchResponse object in the response body. The object may include one or more of the following answer types:

{
    "_type": "SearchResponse",
    "queryContext": {...},
    "rankingResponse": {...},
    "entities": {...},
    "places": {...}
}

Basically, Bing returns any answer it finds that's relevant to the user's query, which is typically a subset of the possible answers. But Bing always returns the following answers in each response:

{
    "_type": "SearchResponse",
    "queryContext": {...},
    "rankingResponse": {...}
}

But if an error occurs, the response body contains an ErrorResponse object. Bing returns an error response for all 400 level HTTP status codes. Read more

{
  "_type": "ErrorResponse", 
  "errors": [
    {
      "code": "InvalidAuthorization", 
      "subCode": "AuthorizationMissing", 
      "message": "Authorization is required.", 
      "moreDetails": "Subscription key is not recognized."
    }
  ]
}

The rest of this topic provides details about each of the answer types in the SearchResponse object.

Note

Because URL formats and parameters are subject to change without notice, use all URLs in Bing search results as-is. You should not take dependencies on the URL format or parameters except where noted.

Entities answer

The entities answer contains a list of entity objects that Bing thought were relevant to the query. Each entity in the list identifies a person, place, or thing. Bing returns well-known entities only. Well-known people may include singers, actors, athletes, models, and others. Places refers to well-known tourist attractions, organizations, and localities such as a cities, states, countries, and regions. Things cover everything else not covered by places and people, such as animals, foods, drinks, books, songs, movies, and more. For information about places such as restaurants, hotels, or other local businesses, see the Places answer.

Dominant entity versus disambiguation entities

The list of entities may contain a single dominant entity, multiple disambiguation entities, or both. The following example fragments show the different entity types. See the entityScenario field.

Dominant-only entity (query is Seattle)

  "entities": {
    "value": [
      {
        "name": "Seattle",
        "entityPresentationInfo": {
          "entityScenario": "DominantEntity",
          "entityTypeHints": [
            "City"
          ]
        },
      }
    ]
  },

Dominant and disambiguation entities (query is Mt Rainier)

  "entities": {
    "value": [
      {
        "id": "https://<host>/api/v7/#Entities.0",
        "name": "Mount Rainier",
        "entityPresentationInfo": {
          "entityScenario": "DominantEntity",
          "entityTypeHints": [
            "Place"
          ]
        },
      },
      {
        "id": "https://<host>/api/v7/#Entities.1",
        "name": "Mount Rainier National Park",
        "entityPresentationInfo": {
          "entityScenario": "DisambiguationItem"
        },
      }
    ]
  },

Disambiguation-only entities (query is Washington)

  "entities": {
    "value": [
      {
        "id": "https://<host>/api/v7/#Entities.0",
        "name": "Washington, D.C.",
        "entityPresentationInfo": {
          "entityScenario": "DisambiguationItem",
          "entityTypeHints": [
            "City"
          ]
        },
      },
      {
        "id": "https://<host>/api/v7/#Entities.1",
        "name": "The Washington Post",
        "entityPresentationInfo": {
          "entityScenario": "DisambiguationItem",
          "entityTypeHints": [
            "Organization"
          ]
        },
      },
      {
        "id": "https://<host>/api/v7/#Entities.2",
        "name": "Washington",
        "entityPresentationInfo": {
          "entityScenario": "DisambiguationItem",
          "entityTypeHints": [
            "State"
          ]
        },
      }
    ]
  },

Bing returns a dominant entity when there is no ambiguity as to which entity satisfies the request. If multiple entities could satisfy the request, the list contains more than one disambiguation entities. For example, if the request uses the generic title of a movie franchise, the list likely contains disambiguation entities. But, if the request specifies a specific title from the franchise, the list likely contains a single dominant entity.

The EntityPresentationInfo object contains information that tells you whether the entity is a dominant entity or a disambiguation entity (see the entityScenario field). The object may also include one or more hints (see the entityTypeHints field) that tell you the entity’s type. The list of hints could contain a single hint such as Movie or a list of hints such as Place, LocalBusiness, Restaurant. Each successive hint in the array narrows the entity's type. But not all entities include type hints.

If the list contains one or more disambiguation entities (the entityScenario field is set to DisambiguationItem), consider displaying a list of entities and letting the user select the one they’re interested in. The Entity object’s name field contains the entity’s name. Use the name along with the URL in the url field, if it exists, or the webSearchUrl field to create a hyperlink. The entity includes the url field only if Bing found a website or webpage for the entity. The URL in the webSearchUrl field takes the user to Bing’s search result page for the entity.

The following answer shows what the JSON response looks like for the query, mt rainier. Most entities include the entity’s name, short description, contractual rules, and URL to Bing’s search results page where the user can get more information about the entity. The optional fields that not all entities include are the image, url, and entityTypeHints fields.

Entity attribution

Entities may include the contractualRules field, which contains one or more attributions that you must apply when you display the entity. Not all entities include rules. If the entity provides contractual rules, you must abide by them.

Entity information typically comes from third parties. You are responsible for ensuring that your use is appropriate; for example, by complying with any creative commons license your user experience relies on.

For information about applying attribution, see Data Attribution.

Places answer

The places answer contains a list of local business entity objects that Bing thought were relevant to the query. Bing returns this answer only when the query specifies the name of a local business or asks for a type of business. For example, microsoft store and restaurants near me. Each place in the list identifies a restaurant, hotel, or other local business.

Note

The Places answer supports only U.S. business locations.

Note

You, or a third party on your behalf, may not use, retain, store, cache, share, or distribute any data from the Places answer for the purpose of testing, developing, training, distributing or making available any non-Microsoft service or feature.

Local aware queries such as restaurant near me require the user's location to provide accurate results. Although optional, you should always provide the user’s location using the X-Search-Location and X-MSEdge-ClientIP headers. The X-Search-Location header uses the user’s geographical coordinates (latitude and longitude).

X-Search-Location: lat:47.806897;long:-122.221304;re:30

If you don’t provide the user’s location and Bing thinks the query would benefit from the user's location, it sets the askUserForLocation field of QueryContext to true.

  "queryContext": {
    "originalQuery": "italian restaurants near me",
    "askUserForLocation": true
  },

The EntityPresentationInfo object contains hints that identify the local entity's type. The list contains a list of hints such as Place, LocalBusiness, Restaurant. Each successive hint in the array narrows the entity's type.

        "entityPresentationInfo": {
          "entityScenario": "ListItem",
          "entityTypeHints": [
            "Place",
            "LocalBusiness",
            "Restaurant"
          ]
        },

The local entity includes the place's name, address, and telephone number. If the URL to the place’s website is known, the entity includes it, too. When you display the entity information, use the URL in the url field to create link that takes the user to the business' website; otherwise, use the URL in webSearchUrl to take the user to Bing’s search results page for the entity.

The following example shows what the JSON response looks like for the query, coffee near me.

  "places": {
    "value": [
      {
        "_type": "Restaurant",
        "id": "https://<host>/api/v7/#Places.0",
        "webSearchUrl": "https://www.bing.com/entityexplore?q=Fourth+Coffee...",
        "name": "Fourth Coffee",
        "url": "http://www.fourthcoffee.com/",
        "entityPresentationInfo": {
          "entityScenario": "ListItem",
          "entityTypeHints": [
            "Place",
            "LocalBusiness",
            "Restaurant"
          ]
        },
        "address": {
          "addressLocality": "Bothell",
          "addressRegion": "WA",
          "postalCode": "98021",
          "addressCountry": "US",
          "neighborhood": "Bothell"
        },
        "telephone": "(425) 555-1234"
      },

      . . .
    
    ]
  },

Note that the address’ neighborhood field may contain an empty string.

Note that the _type field identifies the local entity object's type. The above example shows the object's type as Restaurant. Others object types include Hotel and LocalBusiness.
