keyword "ncbi" gives spurious results only with API

What steps will reproduce the problem?
1.List the entries from youtube that match the keyword ncbi ,"
query = gdata.youtube.service.YouTubeVideoQuery()
query.vq = "ncbi"
feed = yt_service.YouTubeQuery(query)
for entry in feed.entry:
     print entry.media.title.text

Doing this gets mostly garbage results with no relevance to keyword

2. Using a browser and querying the keyword: Returns sensible results connected 
with the National Centre for Biomedical Information (NCBI)

3. Manually constructing a URL also gives meaningful results : for eg. 
http://gdata.youtube.com/feeds/api/videos?q=ncbi

What is the expected output? What do you see instead?
Expected output should contain results pertaining to the NCBI - national centre 
for Biomedical information. Instead I see results like :
Best Ever!!!, Black Eyed Peas - The Time (Dirty Bit) and resulyts with no 
matching keywords

What version of the product are you using?
Latest version 2.0 of gdata youtube API
