They expect the swish-e headers, specifically the Wordcharacters is 
needed to know how to detect words.  Look at DefaultHighlight.pm 
set_match_regexp().

I didn't test, but I think @phrases is an array of arrays.

#!/bin/perl -w
use strict;
use lib '/usr/local/lib/swish-e/perl';
use SWISH::DefaultHighlight;

my $text = "some long text here ";

my @phrases = (
                  [ 'some' ],
                  [ 'text' ],
);

my %settings = ();
my %headers = (
    wordcharacters => 'abcdefghijklmnopqrstuvwxyz',
);

my $sho = new SWISH::DefaultHighlight( \%settings, \%headers );
my $ret = $sho->highlight(\$text, \@phrases, 'swishdescription');
print $text if $ret;

This would be easier and faster unless you need something special that 
that module does:

for my $word (qw/some text/) {
    $text ~= s[\b($word)\b][<b>$1</b>]ig;
}
