Partial match does not add excerpt to results.

Partial match of a word does not trigger excerpt to be shown in search results for example search "Drupal" when the body field contains "Drupalists are awesome..." would show only title of the node where this text was found.

Steps to reproduce:
1. Using search api Solr with partial matching enabled
2. Create a node to index that contains text in long text field
3. Search a word from the long text field that is only a partial match and not a full match of the word in question.

Not sure if this is a bug or intended behavior.
