FWIW, you'll see hits on things like:

a) …
b) …
c) …
d) programming is a…

Or stuff like:

…ph.d. programming…

But they only look at the relevance for the first 100 hits when 
estimating the confidence metric, which isn't really compatible 
with how you can structure ranking in a search engine.

You might get less confidence the further down the ranking list 
you get. E.g the first 100 could give 100% confidence, but then 
as the ranker is running out of "good matches" the number of 
false positives could increase significantly...

Also... the search engine might do a cut-off or use a 
predetermined hit-list for popular searches...

Too many potential sources for significant bias in Tiobe (and 
aggregating results from many search engines does not make that 
better, could even make it worse).
