find on record with '

[nrg software]

i'm doing some finds on a field where there search value could be some odd characters. i've tried adding "quotes" around the search as well.

ex: [search for "nurse's room"]

$cmd->addFindCriterion('afield', '"'.$var.'"');

but it doesn't help, i get a 401 error. if i go into FMP client and run the same search i get back what i expect.
