Funnily enough, it also depends on how the search patterns are given,
if in different argumensts or not...

$ ./src/aptitude search '?name(^emacs24$) ?name(^emacs24$)' -F '%p'
emacs24
emacs24:i386

$ ./src/aptitude search '?name(^emacs24$)' '?name(^emacs24$)' -F '%p'
emacs24
emacs24
emacs24:i386
emacs24:i386

With overlapping patterns...

$ ./src/aptitude search '?name(^emacs24$)
?and(?name(^emacs),?name(24$))' -F '%p'
emacs24
emacs24:i386

$ ./src/aptitude search '?name(^emacs24$)'
'?and(?name(^emacs),?name(24$))' -F '%p'
emacs24
emacs24
emacs24:i386
emacs24:i386


After the fix:

$ ./src/aptitude search '~n^emacs24$' '?and(~n^emacs,~n24$)' -F '%p'
emacs24
emacs24:i386

$ ./src/aptitude search '~n^emacs24$ ?and(~n^emacs,~n24$)' -F '%p'
emacs24
emacs24:i386


Fix:
