I can specify in POD that URI encoding is in effect if that placates  
you, and maybe add a bit about how terms are to be built (based on  
the website).  I also noticed that the esearch POD doesn't have a  
demo in the SYNOPSIS yet (my fault).

However, I think this is all a bit silly.  This is something most  
people already realize and take for granted (it's standard for any  
CGI interface to use URI encoding).

Also, most Entrez users do not use a term like 'BRCA2+Human 
[ORGANISM]'.  They use 'BRCA2 AND Human[ORGANISM]' or 'BRCA2 Human 
[ORGANISM]', the latter which is implicit.  All of this is on the  
Entrez website.
