display searched for text in Solr 6

[win harrington]

I used solr/post to insert some *.txt files intoSolr 6. I can search for words 
in Solr and itreturns the id with the file name.
How do I display the text?
managed-schema has
<field name="_text_" type="text_general" indexed="true" stored="true" 
multiValued="true"/>
<copyField source="*" dest="_text_"/>
Thank you.
