Text search with API v2
With Yandex Search API API v2, you can run queries to the Yandex search database and get a response in deferred (asynchronous) mode. The queries run with REST API and gPRC API. The search results you get depend on the parameters specified in your query.
Queries can be submitted by a user or service account with the search-api.webSearch.user
role.
In response to a deferred query, Yandex Search API returns an Operation object containing the operation info: status, ID, call time, etc.
With the Operation object ID, you can track the query execution status and get the results once the processing is complete.
Query body format
The names of the query body fields are different in REST API and gPRC API: the former uses CamelCase

Response format
In response to a deferred query, Yandex Search API returns an Operation object in the following format:
{
"done": true,
"response": {
"@type": "type.googleapis.com/yandex.cloud.searchapi.v2.WebSearchResponse",
"rawData": "<Base64_encoded_XML_response_body>"
},
"id": "<operation_object_ID>",
"description": "WEB search async",
"createdAt": "2024-10-03T08:07:07Z",
"createdBy": "<subject_ID>",
"modifiedAt": "2024-10-03T08:12:09Z"
}
{
"id": "<operation_object_ID>",
"description": "WEB search async",
"createdAt": "2024-10-03T08:07:07Z",

"done": true,
"response": {
"@type": "type.googleapis.com/yandex.cloud.searchapi.v2.WebSearchResponse",
"rawData": "<Base64_encoded_XML_response_body>"
}
}
The response
object within the Operation object becomes available only after the query is executed on the Yandex Search API side and the done
(operation status) field value changes to true
.
The response
object's rawData
field value contains the Base64
