A footnote to this.
Ken & the guys from Adobe came back to me after my last
comment, and did a bit of a turn around. Ken's helped me through
this with sample code and some pointers in the right direction to
assist me to utilise LUCENE's Russian-stemming capabilities (which
I can confirm do actually work!), as a "pre-processor" which
tokenises documents before Verity indexes them, and then does the
same thing to search strings before passing them to Verity. This
works OK, and is a workable band-aid to the situation.
My next move is to factor Verity out of the equation (and, I
hasten to add, any FUTURE equation involving searching - Russian or
otherwise), and produce a pure Lucene solution.
Thanks Ken and Skip for helping us out on this issue. It's
restored my faith in Adobe.
Cheers.
