# Exceptions

In some cases, you might not want to combine documents. If you set `Combine` to `FieldCheck` or `ReferenceTypeFields`, by default Content combines all documents that do not contain the field, and returns only one set.

To return these results without combining them, set the `CombineIgnoreMissingValue` configuration parameter to `True`. For example:

    [Server]
    CombineIgnoreMissingValue=True
