在Raven中查询数据，查询条件必须在index中。

如果查询条件不在index中就会出现如下异常

                var query = session.DynamicIndexQuery<ServiceProviderCallTransaction>()
                                    .Where(x => x.LocationId == request.Id).ToList()

System.ArgumentException: The field 'LocationId' is not indexed, cannot query on fields that are not indexed

在Raven中创建Index

public class App_ActivityLog : AbstractIndexCreationTask<ActivityLog>

    {

        public App_ActivityLog()

        {

            Map = records => from record in records

                             select new

                             {

                                 Id = record.Id,

                                 ClientId = record.ClientId,

                                 ActivityDate = record.ActivityDate,

                                 CategoryId = record.CategoryId,

                                 NameId = record.NameId,

                                 StaffId = record.StaffId,

                                 Status_Value = record.Status.Value,

                                 LocationId = record.LocationId,

                                 ProcedureCode = record.ProcedureCode,

                                 Affiliation_Value = record.Affiliation.Value,

                                 SourceReferenceId = record.SourceReferenceId,

                                 ClaimId = record.ClaimId,

                                 ProgramTypeId = record.ProgramTypeId

                             };

        }

    }
