SilverStripe\FullTextSearch\Search\Adapters\SearchAdapterInterface::getPrependToCriteriaComponent
Due to the fact that we have filter criteria coming from legacy methods (as well as our Criteria), you may find that you need to prepend (or append) something to your group of Criteria statements.
EG: For Solr, we need to add a "+" between the default filters, and our Criteria.
Signature

- string
