The websites of TV/Print content platforms have become hugely popular. And they get millions of weekly hits. But when it comes to their search bars I believe these sites are unique because the way people perform searches on oprah.com or hgtv.com is very characteristic. (I believe) most people enter phrases from recent issues or shows when searching these sites.
This weekend I saw an innovative product featured on HGTV. I went to their site, performed a keyword search and was impressed to see results sorted by show names (and episode numbers)! Another way to improve search results is by uploading closed captioning and linking it to the search keywords.
