Hey, Kern. First off, I deleted the other place on this site where you posted the same question, but here's what I believe is the answer.
Drupal periodically builds its "search index", which is necessary for search to work. However, if cron isn't running properly, the index won't be created or updated.
So: See about getting help with cron. There could be several things wrong, one of them being (simply) that you don't have it set up! Try the poormanscron module.
