How to get GetDidYouMean results for multiple site ids select in site settings

Hi when I have only one site Id as tags in the list I get correct suggestion result.

But as an example shown below, I am trying to pass mutliple site ids and get their corresponding didyoumean results combined. This is not working 

DidYouMeanResult didyouMean = searchClient.Statistics().GetDidYouMean(queryString, x =>
{
x.Size = 10;
x.Tags = new List { "siteid:3b22a323-013b-497f-aa43-b0754bb18082", "siteid:da0486e5-ba45-4db6-9d99-722a72e4aad7" };
});

I want the results specific to the siteIds passed in the list.
