The Yahoo and Google searches looked for articles with the word "network" in the headline. To customize the Pipe and let me search for other terms instead, I configure the TextInput module so it provides a prompt to the user telling them they can change the default search term.

I then connect a Pipe from this module to input fields in the URLBuilder modules where they have parsed out the search term used in the Yahoo and Google searches.

The final product is done, in less than an hour (well, it would have been if I wasn't so obtuse and curious). You can look at it and run it here. (And please ignore the "old man" avatar -- it's my 10-year-old son's doing and not what I really look like. I just haven't figured out how to change it to something else.)

Endless possibilities

Theoretically, I could add other input fields to change the time searched from one hour to a day, for example, or change the Yahoo section searched from Technology to something else. Or look for the search term in the body of the Google articles instead of the headline. Using all the other modules and ideas from people smarter than me, the possibilities are endless.
