> /export 500 error with multivalued string sort
> ----------------------------------------------
>
> Key: SOLR-16345
> URL: https://issues.apache.org/jira/browse/SOLR-16345
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: query
> Affects Versions: 9.0
> Reporter: Dave Vieglais
> Priority: Major
>
> A 500 error is reported when using the `/export` handler and sorting on a
> multi-valued string field.
> Service is current 9.0 release running under docker.
> Using default schema and test documents:
> ```
> [
> {
> "id": "a"
> },
> {
> "id": "aa",
> "child_ss": [
> "a"
> ]
> }
> ]
> ```
> the request:
> ```
> /export?q={*}:{*}&sort=child_ss%20asc&fl=id,child_ss
> ```
> results in a 500 error with no response body.
> Using the `/select` endpoint works as expected:
> ```
> /select?q={*}:{*}&sort=child_ss%20asc&fl=id,child_ss
> ```
> Response:
> ```
> {
> "responseHeader": {
> "zkConnected": true,
> "status": 0,
> "QTime": 0,
> "params": {
> "q": "*:*",
> "fl": "id,child_ss",
> "sort": "child_ss asc"
> }
> },
> "response": {
> "numFound": 2,
> "start": 0,
> "numFoundExact": true,
> "docs": [
> {
> "id": "aa",
> "child_ss": [
> "a"
> ]
> },
> {
> "id": "a"
> }
> ]
> }
> }
> ```
