Hmmm...
Here is the code from around line 201 in search.rb:

def set_from_sources(sources)
final = Set.new
sources.each do |source|
p = Page.find_by_id source
h = YAML.load(p.data)
final.merge h.keys
end
final
end

Here is line 107 in search.rb:
gamma[:D] = set_from_sources(gamma[:C]) - (txv[:a] + txv[:b])

If sources is empty from the form data not getting passed to it or
sources getting assigned invalid data could that be causing the error?
Please ignore my rails stupidity. Thanks
