This example connects a text user input module to string tokenizer to create an array of search terms. The term delimiter is a comma. These terms are passed into a Loop module containing a Yahoo! Search sub-module.
The Search sub-module is site restricted to Wikipedia, and the loop is configured to only output the first result for each search.
If you enter the string "frog,vanilla,pulp fiction" into the text input box, the resulting feed will have three items.
