How Can I Increase a 40 Packages Limit in Aptitude?

[Chime Hart]

Hi All: Many times when I cannot grab a package in apt, I run aptitude. Quite 
often it will say something like "there are 89 packages but limit is 40"  I 
tried looking around for an aptitude config where I can increase or remove that 
limit. I am in Debian SID. Thanks so much in advance.
