XML format of a text search response

Written by
Updated at November 20, 2024

In response to a text search query, Yandex Search API can return a UTF-8 encoded XML file with search results. The service returns an XML response for text queries processed both via API v1 and API v2.

Alert

You can get a maximum of 1,000 search results per search query. Depending on the docs-in-group attribute value, each result may contain one to three documents. The maximum number of search results pages depends on the number of groups of documents per page, which is defined by the groups-on-page attribute. For example, if the groups-on-page attribute is set to 10, a maximum of 100 pages with search results can be generated.

Files consist of grouping tags such as request (aggregate information on search query parameters) and response (search query handling results).

Below is the general structure of the resulting XML document with examples of values.

Warning

This structure is provided for information purposes only and contains mutually exclusive elements.
