[CWB] Multiple constraints on structural attributes

[Ruprecht von Waldenfels]

Dear All,
this seems like a trivial question, but I couldn't find it in the 
manual: how do you combine constraints like

"this" ::match.chapter_author=".*Kerski"
and
"this" ::match.chapter_year="1985"
?

I tried something like

"this" ::match.chapter_author=".*Kerski" & ::match.chapter_year="1985"

but of course this didn't work...

Thanks and best!
Ruprecht
