Two things:
1) if you want face to match interface, you need max value to be at least 4.
2) you probably have the factory symmetrically or on Query analyzer. You
probably want it on Index analyzer side only. Otherwise you are trying to
match any 3-letter query substring against yoir index.
Admin UI analysis screen will show that to you.
