Issue

I am trying to use the new $search feature, but I get the error "Unable to cast object of type 'System.Linq.Expressions.ConstantExpression' to type 'System.Linq.Expressions.MethodCallExpression'."

I uploaded a test project that can reproduce the issue. Test query: https://localhost:7222/students?$search=Norman

Version Info

Target Framework: .NET 6.0 Pacakges: AutoMapper.AspNetCore.OData.EFCore: 3.0.1 AutoMapper.Extensions.Microsoft.DependencyInjection: 11.0.0 Microsoft.EntityFrameworkCore.SqlServer: 6.0.2

Not sure what's goin on here. Your search binder is not being called for some reason. Maybe start with the sample here, add your code and see when it breaks.

I don't see anything in the dev blog which suggests you're missing something.

Maybe post here when you figure out the difference?
