def create url
  ::URI.parse url[-1] == ?/ ? url : "#{url}/"
end

#escape_query_value(s) ⇒ Object

Performs URI escaping so that you can construct proper query strings faster. Use this rather than the cgi.rb version since it’s faster. (Stolen from Rack).

def escape_query_value(s)
  s.to_s.gsub(/([^ a-zA-Z0-9_.-]+)/u) {
    '%'+$1.unpack('H2'*bytesize($1)).join('%').upcase
  }.tr(' ', '+')
end

#params_to_solr(params, escape = true) ⇒ Object

Creates a Solr based query string. Keys that have arrays values are set multiple times:

params_to_solr(:q => 'query', :fq => ['a', 'b'])

is converted to:

?q=query&fq=a&fq=b
