Solango Tips and Gotchas

For the last week or so I've been wrapping my brain around Solr and Solango. The whole time that I've been doing this I've had the feeling that they can do awesome, powerful things but they're documentation is so poor that I couldn't figure anything out beyond the basic examples. Ultimately I had to dig through a bunch of code and do some experimentation. Now that I've finally figured out how to do what I've been trying to do and have wrapped my brain around some of the trickier bits I'm going to share some of the gotchas and solutions I've found.
