Specialist search engines - part 1

I looked for videos on the topic of "Amazon forests" in YouTube and Blinkz. Looking for the Exact Phrase in Blinkz using BBC returned me nothing, I needed to be less restrictive. I preferred the advanced search on YouTube, but found it very laborious moving the location - in this case to 'near London' so that I could fairly compare it to the Blinkz search. When I did this both providers achieved about the same number of hits. I found it much easier to restrict content providers than location. I have spent ages on Module 4, so will complete this exercise next session.
