[Slapt-get-user] How does search work?

[Scott Lockwood]

Also, that's odd. Results like lvm- should not have been returned for
"^lvm2*"... That makes me wonder if slapt-get isn't handling the regex
correctly...

I tried it and I got

kernel 97% slapt-get --search '^lvm2*'
lvm-1.0.8-i486-1 [inst=no]: lvm (Logical Volume Manager)
lvm2-2.01.09-i486-1 [inst=yes]: lvm2 (Logical Volume Manager version 2)

...but even if this does not give me what I would expect either, I'm really
interested in a search pattern for lvm (not lvm2) that I can use in my
EXCLUDE list. That is why I was trying ^lvm-.
