public function SearchApiSolrField::isSortable in Search API Solr 7

Determines whether a field is suitable for sorting.

In order for a field to yield useful sorted results in Solr, it must be indexed, not multivalued, and not tokenized. It's ok if a field is tokenized and yields only one token, but there's no general way to check for that.

Return value

bool Whether the field is suitable for sorting.
