Of course because this is a database of Russian NAMES, but NOT a database of surnames.

sure, it's how text search mapping works.
Could you please detalize?
Of course I can create all word-forms of all Russian names using ispell and then - subtract this full list from Ispell dictionary (so I will remove "Ivan", "Ivanami" etc. from it). But possily tsearch2 has this subtraction algorythm already.
Dmitry, seems your company could be my client :)
Not now, thank you. Maybe later.
