Unable to filter IPackageSearchMetadata by SearchFilter.SupportedFrameworks

[gokceng-intertech]

Hi,
I'm trying to get package metadata by the supported frameworks:

ILogger logger = NullLogger.Instance;
SourceRepository repository = Repository.Factory.GetCoreV3("https://api.nuget.org/v3/index.json");
PackageSearchResource searchResource = await repository.GetResourceAsync<PackageSearchResource>();
var searchFilter = new SearchFilter(includePrerelease: false)
{
    IncludeDelisted = false,
    SupportedFrameworks = new[] { "net7.0" },
};

IEnumerable<IPackageSearchMetadata> searchMetadata = await searchResource.SearchAsync("Microsoft.EntityFrameworkCore.Abstractions", searchFilter, 0, 1, logger, CancellationToken.None);

foreach (IPackageSearchMetadata m in searchMetadata)
{
    Console.WriteLine($"Found version {m.Identity}");
}

Output:

Found version Microsoft.EntityFrameworkCore.Abstractions.8.0.2

But the given version doesn't support net7.0, it supports net8.0 only:
https://www.nuget.org/packages/Microsoft.EntityFrameworkCore.Abstractions/8.0.2#supportedframeworks-body-tab

Is there something I'm using incorrectly or is this not supported?
Thanks in advance,
Gokcen
