You can see an example of similar use at: http://www.solr-start.com/javadoc/solr-lucene/index.html (search box).
The corresponding schema is here: https://github.com/arafalov/Solr-Javadoc/blob/master/JavadocIndex/JavadocCollection/conf/schema.xml#L24 . It does have some extra special-case stuff to allow to search by the fragments, but the general use case is the same.
