I dont totally agree with that. We've had some success in applying only 
the first two steps of the English (Porter) stemmer
to large English web corpuses. Many submissions to last year's TREC 
Terabyte track didnt use stemming at all.
It would also appear to be a similar approach to what Google is doing. 
The first two steps only drops plurals and tense suffixes.
