Spellcheck support.
Don't return a collation if spelledCorrectly is true.
Actually, this is a better condition.
Allow the user to optionally tokenize the query they're collating.
Allows the use of POST requests instead of GET. Needs an upadated version of rsolr though.
You can now submit your requests using GET or POST verb
Now we use ALWAYS POST for requests
ERB support for config YAML
Don't go looking for collations when no spellcheck results are present.
