Holumbus.Index.CompactSmallDocuments

A simple version of Holumbus.Index.Documents. This implementation is only for reading a document table in the search part of an application. The mapping of URIs to DocIds is only required during index building, not when accessing the index. So this 2. mapping is removed in this implementation for saving space

Documents type

newtype SmallDocuments a

The table to store the document descriptions

This table does not contain the reverse map from URIs do DocIds, this reverse map is only needed when crawling, not for searching the index. As a consequence, most of the indes operations are not implemented
