Hi all:
First question:
If I write:
\defbibfilter{general}{\( \keyword{General} \) \and \type{electronic} \and
\not \type{book}}
It works fine, but if I write
\defbibfilter{general}{\keyword{General} \and \not \type{electronic}}
It includes the type electronic. I can use the first command, but I don't
know why I can't use the second —is more easy to use—.
The second question:
I have two filters in preamble:
\defbibfilter{general}{\( \keyword{General} \) \and \type{book} \and \not
\type{electronic}}
\defbibfilter{online}{\( \keyword{General} \) \and \type{electronic} \and
\not \type{book}
The first works, the second not. Why? I don't know…
Regards!
