Solr-Retrieve name of document where the word is found

Question

I am using queries (Solr Admin) to search words through two text documents that are in my HDFS. How can i retrieve the name of the document that the word is found in. I am using this project https://github.com/lucidworks/hadoop-solr

I am creating a collection using bin/solr -e cloud and i am using "data_driven_schema_configs" from server/solr/configsets/ directory.

I tryied adding <field name="fileName" type="string" indexed="true" stored="true" /> inside managed-schema at ~/solr-6.1.0/server/solr/configsets/data_driven_schema_configs/conf, and also change it name to schema.xml, but in this directory there isn't any dataConfig file to add <field column="file" name="fileName"/> as i see it in some other posts with similar questions, but not for SolrCloud, so i don't know if that i am trying is correct. What changes, and in which directories, i have to do, to be able to make it happen.

Example: I am searching the word "greatest" which can found in both documents. How can i see in which document is every result, sample1.txt or sample2.txt

Same thing I said when you mentioned this question on IRC:

Your Solr schema must contain a field where you put the name, set to stored="true", and you must include that field, with a relevant value, in every document when you index. Most schema changes require a full reindex.
