IndexDefinition definition = new IndexDefinition
{
  Maps = new HashSet<string> { @"from order in docs.Orders
                      select new 
                      {

store.Maintenance.Send(new PutIndexesOperation(definition));

}
.ToIndexDefinition(store.Conventions);
store.Maintenance.Send(new PutIndexesOperation(definition));
