    3535   Harvested metadata records are processed centrally and ingested (inserted) into the discovery index database, which stores the documents in their entirety (to enable full-text searching), but also pulls out pre-defined fields within them to enable specific types of searhes (e.g. spatial extent, time periods). The database is held as a set of relational database tables within a database server, but with original documents preserved in their native format (XML).

    3838   A piece of software run alongside the discovery database, which offers a "presentation-less" service to handle search requests. On receipt of an appropriately-constructed XML message from the '''search interface''', it will carry out a search of the discovery database and construct a search response message, which is sent back to the search interface. Similarly, it also handles requests for returning specific documents in the database : a request is received in XML, and an appropriate response is sent back to the sender. In all cases, messages (request/response) are exchanged in XML, with all presentational formatting handled by the search interface (which itself may be part of a 3rd party web portal).
