queryRecordType with an "or" condition

I need an Expression Rule that has an or condition for a filed.

I have a list of clergy assignments and I need to pull all current assignments and those that terminated over the last year.  The record type, CPMA Clergy Position has a termination date for the assignment, clergyPositionTermEnd which is a date formatted field.  If the assignment is for a fixed term, then there is a future date in the field.  If the assignment is a permanent assignment, then the field date is null.  

The or function would look like this.

or(
    RecordType!CPMA Clergy Position.field.clergypositiontermend >= today()-365,
    isNullOrEmpty(RecordType!CPMA Clergy Position.field.clergypositiontermend)
    )

However, I do not understand how to use this inside an Expression Rule.  My Expression Rule using the queryRecordType function looks like this.

if(
  a!isNotNullOrEmpty(ri!clergyId),
  a!queryRecordType(
    recordType: 'recordType!CPMA Clergy Position',
    pagingInfo: a!pagingInfo(startIndex: 1, batchSize: 5000),
    filters: {
      a!queryFilter(
        field: 'recordType!CPMA Clergy Position.fields.clergyId',
        operator: "=",
        value: ri!clergyId
      ),
      a!queryFilter(
        field: 'recordType!CPMA Clergy Position.fields.clergypositiontermend',
        operator: ">=",
        value: today()-365
      ),
      a!queryFilter(
        field:'recordType!CPMA Clergy Position.fields.clergypositiontermend',
        operator: "is null"
      )
      
    }
  ),
  null
).data

However, it doesn't work.  No values are returned. I am assuming that Appian treats the listing of queryFilters as an "and" condition.  I have tried using the If function to check to see if the clergyPositionTermEnd field is null, but that only pulls records with a value in the field. 

Thanks for you help!
