I just got my first nominatim instance up and running! Very exciting. I've written a little PHP script to just return the results from Geocode.lookup(). Could someone explain what some of these parameters mean? I couldn't find a complete explanation on the wiki. In particular, I've noted the ones I'm unsure of with '?'s

As you also ask for (at least for me) obvious details, I like to ask if you already read: http://wiki.openstreetmap.org/wiki/Nominatim#Parameters ?

The source code now contains a short description of these fields. I also recommend to have a look at the SOTM'13 Nominatim presentation where a bit more on the background of the database schema is explained.
