If I understand your question, I think that the first answer was exactly correct.
You don't need to use Lucene for persistence in order to use it for searching. By setting the fields to be non-stored, Lucene only constructs the index for those fields, and doesn't save the full text of the field. For example, we store the text we are searching in an RDBMS, and only use Lucene for the full-text index. When we need to retrieve the actual document, we don't go to Lucene; we go to the RDBMS.
This doesn't require any code changes at all; you just set the fields to non-stored when you index the documents.
Lucene still does need an index, somewhere, in order to search, and Lucene manages the format of the index, so you will still need to use IndexWriter and IndexReader, and some Directory subclass, in order for Lucene to have a place to store its index. You can create a new flavor of Directory if you want Lucene to store its index files somewhere more exotic than the standard classes allow.
