We’re not supporting any fancy operators, but we did want to allow phrases to be specified in double quotes. It’s an easy enough operation, but I googled to see if anyone was offering a particularly efficient way to do that in ruby.

Nothing came up and since I’ve not posted in a while I thought I’d offer it for anyone else in that situation.

def split_params(params)
  # Find all phrases enclosed in quotes and pull 
  # them into a flat array of phrases
  phrases = params.scan(/"(.*?)"/).flatten
 
  # Remove those phrases from the original string
  left_over = params.gsub(/"(.*?)"/, "").squeeze(" ").strip
 
  # Break up the remaining keywords on whitespace
  keywords = left_over.split(/ /)
 
  # Return one single array of key phrases
  keywords + phrases
end
