DotNet Core Azure Search SDK - filtering results

We are trying to implement Filter functionality into Azure (Cognitive) Search. I was hoping to find some nice SDK methods that hide all the ugly parts, but so far the only example I found looks like this (source):

SearchParameters parameters = new SearchParameters()
{
    Filter = String.Format("groupIds/any(p:search.in(p, '{0}'))", string.Join(",", groups.Select(g => g.ToString()))),
    Select = new[] { "application essays" }
};

I was wondering, whether I am missing some docs. Or maybe it is on the roadmap?

Check out our new Azure.Search.Documents SDK we released last month. It does have OData filter helps as you can find here:

int stars = 4;
SearchOptions options = new SearchOptions
{
    // Filter to only Rating greater than or equal our preference
    Filter = SearchFilter.Create($"Rating ge {stars}"),
    Size = 5, // Take only 5 results
    OrderBy = { "Rating desc" } // Sort by Rating from high to low
};

It'll escape string parameters correctly. The OData $filter syntax still requires raw input, but the type helpers in the formattable string should make your situation easier: you don't have to worry about escaping values yourself.
