In the Livelink design the index was capable of defining "regions" which in effect were the XML elements for the metadata and roughly equated to the SQL database columns. I assume that Lucene has a similar capability?
I'm not sure how this maps to Lucene exactly. A Lucene index is a series of "documents" each of which has one or more named "fields". Fields are chunked into one or more "terms". That really summarizes the structure succinctly. Imposing hierarchy would require clever use of documents and fields, or perhaps other games with multiple indexes representing different aspects of a Slide 'resource'.
I guess a field is analogous to a database column or "region"?
