The only cases I can think you might be referring to are two different
submissions of patches based on Andy Stark's implementation of the
Paice/Husk stemmer (not the Porter stemmer).  The problem there is that
this implementation has no explicit licence, which means we simply can't
use it:

Yeah right, Its was Paice/Husk stemmer implementation( Andy Stark's),

Now that if i code a Krovetz Implementation from scratch, than possibly i
have to use
the api and backend calls from xapian api rather than making it as
independent module
and similar to stem.h in namespace xapian.

I don't think the backends would be useful for a stemmer.  Even for a
dictionary-based stemmer you'd probably want to have the dictionary
in memory while indexing, since you have to look up every word in
every document.

The only part of the Xapian API you're likely to find useful is the
Unicode support (and if you need such functionality it would be better
to use this than duplicate it).

Cheers,
