QueryOption Search in Graph API for email address

问题

I would like to search in my sent folder for every email that is sent to "john.smith1@gmail.com"

I tried the following

 List<QueryOption> queryOptions = new List<QueryOption> { new QueryOption("$search", "john.smith1@gmail.com") }; 

List<QueryOption> queryOptions = new List<QueryOption> { new QueryOption("$search", "john.smith1%40gmail.com") }; 

 List<QueryOption> queryOptions = new List<QueryOption> { new QueryOption("$search", "to:john.smith1@gmail.com") }; 

List<QueryOption> queryOptions = new List<QueryOption> { new QueryOption("$search", "to:john.smith1%40gmail.com") }; 

  var messages = await client.Users["myuser@mydomain.com"].Messages.Request(queryOptions ).GetAsync();

none of the above works. It complains of any non alpha character ( it seems it does not accept number, dot, ":" )

Any advices? Thanks.

Use it this way -

List<QueryOption> queryOptions = new List<QueryOption>
{                                                  
    new QueryOption("$search", "%22abcd02%40gmail.com%22") 
}; 

%22 is nothing but the double quotes. We are just concatenating it to work.
