No "Multiple Field Settings" for outputting fields with multiple records

Fields that contain multiple records are not serializeable in the View interface, even though they are filterable individually. As an example, taxonomy terms. Apache Solr Views has no difficulty filtering for each taxonomy term individually, but when displaying the field containing the taxonomy terms it does not present an option for multiple outputs. Even simple changes like comma-delimiting the list are not currently possible.

Steps to reproduce:

1. Configure Apache Solr to index a certain content type
2. Create an Apache Solr View to display certain fields from that content type based on the results of a solr search
3. When editing the view, try to adjust the output of a multiple field (such as one containing taxonomy terms) to change its Multiple Field Settings

Expected results: See a dropdown for Multiple Field Settings where Display Type can be adjusted, including basic delimiting of the multiple field
Actual results: No Multiple Field Settings exist
