Can you give a short example of the code you are using?  I don't seem to
follow what the problem is, exactly.

#!perl -wl
use Search::Dict;

$key = 'abandon';
open(FH1, ':b') || die $!;
look(*FH1, $key);
chomp($b = <FH1>);
print $b;

$key = '100002880';
open(FH2, ':c') || die $!;
look(*FH2, $key, 1);
chomp($c = <FH2>);
print $c;

This code works fine for me, and works every time.  It prints:

abandon,103826829
100002880,'(living things collectively; "the oceans are teeming with life")'
