I realise this is confusing but indexing code is duplicated in 
cfg.d/indexing.pl.

Have you changed:
$c->{indexing}->{freetext_min_word_size} = 3;

To 1 as well?

There might be other places causing problems too - I'll have to investigate.
(We have an open bug w.r.t. short terms, for instance searching for a 
username with less than 4 chars doesn't work at the moment)

All the best,
Tim.
