Question

Is there any existing implementation for query expansion in Perl?
By query expansion I mean, when the user enter a query in our database
it will expand the search based on related terms.

In principle we have a XML file (e.g. MESH) with which
we want to refer to for query expansion.

Bio::DB::MeSH – Term retrieval from a Web MeSH database

my $mesh = Bio::DB::MeSH->new();
my $term = $mesh->get_exact_term('Butter');
print $term->description;
