Now, we need to configure the Term Extractor module to work correctly within Yahoo Pipes.
Because we only want to send Flickr a single term, we need to change "Emit results as ..." from "single item" to "list".
Next, we need to change the module from assigning "all" results to assigning "first" results. This tells Yahoo! Pipes to generate a list of keywords and only send the first item from the list to Flickr.
The loop element should default to "item.loop:termextraction" and should not be changed.
