[BUG] Search: Support model serialization

Library name and version

using Azure.Search.Documents 11.0.0

Describe the bug

Calling SearchAsSync Giving a object of SearchResult<T> on serializing this document. In Facets only value is getting serialized other properties (count , to , from ) are getting added to the actual string

Sample Code :

        SearchOptions searchOption = new SearchOptions();
        searchOption.IncludeTotalCount = true;
        searchOption.QueryType = SearchQueryType.Full;
        searchOption.Facets.Add("someField");
        SearchResults<T> results = await searchClient.SearchAsync<T>("*", searchOptions)        
        string result = JsonSerializer.Serialize(results);
        Console.WriteLine(result);

Expected behavior

should add all values of facets (count, to , from) on seralization of searchResult.

Actual behavior

If you see in facet object just value is coming (count, from , to) are not coming.

{“TotalCount”:20,“Coverage”:null,“Facets”:{“someValue”:[{“value”:“111”},{“value”:“1111”},{“value”:“11111”},{“value”:“1119”},{“value”:“1219”},{“value”:“123456”},{“value”:“126”},{“value”:“1260”},{“value”:“1267”},{“value”:“1268”}]}}

Reproduction Steps

Given a sample code.

Environment

.Net versio 6 Visual Studio 2022

Hi @manijndl7. Thank you for your feedback.

Currently we intentionally do not support serialization/deserialization for Azure SDK model types due to the challenges associated with guaranteeing serialization compatibility across versions. While our public APIs have strong compatibility guarantees, serialization compatibility brings a different set of challenges. As a result, this is a feature that needs careful design and approval by our API governance board. We’ve had similar feedback in the past, so we’re aware this is a feature that there is interested in. I’ve tagged this as a feature request and moved this to the backlog for consideration.

As a work-around for serialization in the meantime, you may want to consider calling results.GetRawResponse().Content. This gives you a BinaryData instance that represents the service response, allowing you to retrieve the JSON content as a string or write it out to a Utf8JsonWriter or similar.

There is a new feature that will soon be released to enable this capability: https://github.com/Azure/azure-sdk-for-net/issues/16977. Mark this problem as duplicate and close.
