Can someone confirm whether, in network entrez (Not the WWW version),
under advanced search, that "-" is the correct term for Boolean NOT ?
Since "NOT" and "BUTNOT" don't do anything, but "-" does, I assume this
is what to use - but I would like to be sure :) It would have been sensible
for NCBI to use the same syntax on Network and WWW entrez, especially
since the documentation for the former leaves a lot to be desired (I know,
I know, it's free software).
Thanks
Andrew
