But is the author

"lahaye, tim & jenkins, jerry"

Like, one freak with an ampersand in their name

Or

"lahaye, tim"

and

"jenkins, jerry"

Two people with no ampersand in their names?

Also, what about tags? Is the tag "medieval, science, welding" a single tag containing all three, or three separate fields?

Just to clarify - Are you talking about a folder called "lahaye, tim & jenkins, jerry"?

With a book inside?

I am not talking about this. There is no problem calling a folder "blah&blah&blah&blah"

I am refering to the details view in windows explorer, which allows you to use columns such as author, tags, title etc. If you attempt to filter ampersand/comma delimited fields, they appear as a single field, unless they are delimited by the semicolon.
