Searching - What am I not understanding

[Barreti]

I was looking for info on Antifreeze and remebered there being something about colour in the threads.
So I searched for "antifreeze pink" and found this
http://www.pistonheads.co.uk/gassing/topic.asp?h=0...

So how come when I then search for "antifreeze audi" or "antifreeze G12" nothing is found although both words can clearly be seen in the post from Spend next to the bottom.


Thanks

Any ideas guys?
