Re: An example to query PMID given GEO accession number?

I assume you read the documentation and understand what the query is doing?
Is your Geo UID a member of a dataset or series? - that's what the query is restricting to when it filters the entry-type. I assume that your editing of the query and removing "OR gds[ETYP]" means that's it's part of a dataset.
Also what do you mean by the "correct" PMID? These are often updated/deprecated so you can get different results on successive days.

Why can't I get the correct PMID?

~$ ./main.pl
Query translation: GSE39684[ACCN] AND gse[ETYP] Count = 1
200039684
~$ cat main.pl
#!/usr/bin/env perl

use strict;
use warnings;
use autodie;

use FindBin;
use lib "$FindBin::Bin/.";
use Bio::DB::EUtilities;

# want to get PMID 23028701
my $geo        = "GSE39684";
my $factory = Bio::DB::EUtilities->new(
  -eutil   => 'esearch',
  -db      => 'gds',
  #-term    => "${geo}[ACCN] AND (gse[ETYP] OR gds[ETYP])",
  -term    => "${geo}[ACCN] AND (gse[ETYP])",
  -email   => '[email protected]',
);

# query terms are mapped; what's the actual query?
print "Query translation: ",$factory->get_query_translation,"\n";
# query hits
print "Count = ",$factory->get_count,"\n"; # UIDs my @ids = $factory->get_ids; print "@ids\n";
