If by retrieve you mean get all the gene expression values (as from
the export page), you'll have to first get all the raw data sets into
a single experiment. The raw data set list doesn't let you do filtering
on the sample descriptions, but only because it's not in the list of
things you can filter on. Some rather minor changes to raw.inc.php is
all that should be needed.
Genes and samples are as good as orthagonal, so I'm not sure what
it would mean to search for a single gene based on anything that
has to do with samples. But at least you can get a list of all genes
that appear on arrays which have been used with a set of samples,
if you can get the corresponding raw data sets into an experiment.
