languages |
string |
The list of language codes (defined in ISO 639) to run the query with, for instance `en`. |

indent |
boolean |
Enables indenting of JSON results. |

Schema.org compatibility
The response uses the vocabulary hosted at
schema.org, with limited extensions (for
example, resultScore
) that are compatible with schema.org vocabulary.
For more details about these extensions, see
List of schema extensions.
For each of the Schema.org types (such as Person
) and properties (such as
name
) there is a corresponding full URI, as in the following examples:
- Person -> http://schema.org/Person
Thing -> http://schema.org/Thing
name -> http://schema.org/name
description -> http://schema.org/description
Types and properties defined as Google schema extensions can be expanded with http://schema.googleapis.com. For example,
- EntitySearchResult -> http://schema.googleapis.com/EntitySearchResult
- detailedDescription -> http://schema.googleapis.com/detailedDescription
The documentation for each type and property is available at the corresponding URI.
