The mark of a bad search implementation… this is almost always 99% indicative of a naive implementation of search using MySQL FULLTEXT.
This is usually a sign of bad outsourced-overseas development and a company run by “business”-only people. I looked at their About page to find out, and found this gem as one of their “three goals”:

So how, exactly, am I supposed to find the many C4 videos? The stupid FULLTEXT search doesn’t work.
The only way I found was to click the c41 tag on one of the videos I actually knew about — but only after being frustrated, giving up, and starting to write this post. Nobody except geeks knows what “tags” are… that’s not a solution.
Search is a critical navigation element. Don’t slack on it.
