SqlFunctions.StringConvert((Double)person.YearsOld).Contains(searchText)

this must work fine the problem is that when you execute que query  Ideablade throw an exception

"Execution of query against the server was successful but execution of query against the local cache failed"
Target Site {System.String StringConvert(System.Nullable`1[System.Double])}
{"This function can only be invoked from LINQ to Entities."}

if I change the query strategy to datasource only, the query is fine, and there is No exception, is there Ideablade 
support for SqlFunctions, because they work for LINQ to Entities

var query = Entities.DefaultManager.GetQuery<People>().AsQueryable();

and I want to filter some integers and  doubles (for example person years old and Money ) with a textbox value

String searchText = TextEdit.Text;

query = query.Where(person =>  person.YearsOld.ToString().Contains(searchText) || 
person.Money.ToString().Contains(searchText)
);
