Well I'll tell you why I was trying to use URL-encoded parameters, if
that helps you any.
I read the pod for EUtilities but all the examples have very simple
-term s defined with just a single word. So I wonder how I'm supposed to
make an 'AND' term. I also have no idea what utilities I'm supposed to
use, or what databases etc. I need to get the answer I want.
The POD points me here:
Combined with the EUtilities synopsis I know I'm supposed to start with
esearch so I look at:
And figure out what my terms are supposed to be.
Then I test some example terms in my web browser using the esearch base
url (http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?) to see
if they work, and copy/paste the terms into my EUtilities-using perl
script, replacing variable terms with perl variables.
Then I find that my terms don't work, ask you about it, and you fail to
tell me I should be testing my terms at
If you think I'm stupid, fine, but I'm probably not the only stupid
person on the planet. Which is why I suggested a POD addition. You don't
have to make any POD change if you don't want to. I simply thought it
might help avoid anyone 'badgering' you in the future with a similar
