In EntitySpaces you can specify filter to load data. I've wrote the following code
EmployeesCollection collection = new EmployeesCollection();
Collection.Query.LastName.Like("A%")
collection.Query.Load();
and couldn't understand why the filter doesn't work.
The reason is that functions similat to Like, LessThan return esWhereItem that will work only after they passed to esDynamicQuery.Where(Object[]()) method.
So the correct code must be
Dim collection As EmployeesCollection = New EmployeesCollection()
collection.Query.Where(collection.Query.LastName.Like("A%"))
collection.Query.Load()
