It's a Solr reference manual [pdf] based on some distilled references from Apache Solr 3 Enterprise Search Server from Packt Publishing, a book that Eric co-authored with David Smiley. The motivation behind this manual is simply to help with some of the logical inconsistencies in the parameter names (e.g. query type parameter is "qt" but query parser is "deftype"). The reference is meant to help you remember these oddities that are hard to codify in your brain.
The references have page numbers that correspond to sections of the book, so it can still be useful if you've got a good grasp of solr, but it's primarily geared toward people who have the book. That's what the description says:
This appendix is a convenient reference for common search related request
parameters. It is assumed you already read the related material in the book and are
just looking for something to jog your memory.
Reference categories include:
- Core Search
- Dismax Query Parser
- Lucene Query Parser
- Luceen Query Syntax
- Spell Checking
- Misc. Non-Search
