By data, I mean documents which are to be indexed. Some fields can be stored="true" but that doesn’t matter.
For example: App1 creates an object (AppObj) to be indexed and sends it to SOLR via solrj. Some of the attributes of this object can be declared to be used for storage. Now, my understanding is data and indexes generated on data are two separate things. In my particular example, all fields have stored="true" but only selected fields have indexed="true". My expectation is, indexes are stored separately from data because indexes can be generated by different techniques/algorithms but data/documents remain unchanged. Please correct me if my understanding is not correct.

What do you mean by "data" as opposed to "indexes"? Are you talking about where Lucene puts stored="true" fields? If not, what do you mean by "data"? If you are talking about where Lucene puts the stored="true" bits the no, there's no way to segregate that our from the other files that make up a segment.
