Very interesting observation. The basic problem is that Google is
smarter than Netfrastructure.
I mentioned plural handing as important -- and some day I might get to
it. Google has the
native wit, whether in retrieval, scoring, or both I can't say, to
recognize that from a search
perspective, blob and blobs are pretty much the same thing.
Netfrastructure doesn't. It
does, incidentally, support external search engines, which is about
10,000 times more
complicated than it might seem.

Netfrastructure implements Alta Vista semantics: + and - are honored,
phrases aren't
played with, and upper case must match upper case while lower case
matches either
case. An application, of course, is free to preprocess a search request
to support other
syntax conventions. Google, however, is more forgiving in almost all
dimensions and
Alta Vista and Netfrastructure, and I wouldn't presume to argue against
Google.
