-Structured target profiles -- Zeerex.
-Normalization of records -- test if libXSLT is fast enough to:
- -- Extract Subject headings, titles, dates, authors for facets and display
- -- Merge keys for relevance ranking, etc.
- -- Also normalize to UTF-8.
-Implement timeout of sessions, so they don't sit there forever (simple).
-Sort by title, date, author. Parameter to 'show' webservice command.
-Additional facets. At least do 'author'.. think about making it general.
-Support for 'blocking' requests, at least for record display before first records
- are retrieved (to reduce polling).
-Implement detection of 'search complete', so client knows when to stop polling.
-Full record retrieval.
-Implement hitsbytarget function to emulate traditional LOT-style U/I
