I need to parse and display solr facets which are returned in either JSON or Ruby formar:
Collections: [ "a", 1, "b", 2, "c", 3, "d", 4, ... ]
into
{"a"=>1, "b"=>2, "c"=>3, "d"=>4}
What is the cleanest way?

EDIT: Well now that we know what you actually want, a hash ...
collections = ["a", 1, "b", 2, "c", 3, "d", 4]
Hash[*collections]
# => {"a"=>1, "b"=>2, "c"=>3, "d"=>4}
Original answer: I may not understand your goal but...
collections = ["a", 1, "b", 2, "c", 3, "d", 4]
collections.each_slice(2).map{ |(x, y)| "#{x} - #{y}" }
# => ["a - 1", "b - 2", "c - 3", "d - 4"]

What i see you want to do is maybe a hash ? {a => "1", b => "2"} ??
If so, read below:
collections = [ "a", 1, "b", 2, "c", 3, "d", 4]
result = Hash[*collections.flatten]
result prints {"a"=>1, "b"=>2, "c"=>3, "d"=>4}
