So I was using the module finder to find all "carousel" modules, which returns four results (if you change the Title to Contains). However, then I wanted to link someone to this, but the regular search only returns two modules: http://drupalmodules.com/search/node/car...

This is a limitation of Drupal's word-based search algorithm. Because Drupal only compares exact words, it can't make a connection between "carousel", "jCarousel", and "Nodecarousel".
Module Finder doesn't have this problem because it compares everything at the character level.
Unfortunately, there isn't an easy way to link to Module Finder results at the moment.
