[Koha] StopWords List

Under "System Preferences > Searching Preferences" we can turn "QueryRemoveStopwords" on or off. The explanation for that option reads "If ON, stopwords listed in the Administration area will be removed from queries" . But I can't for the life of me FIND the "stopwords listed in the Administration area"! I am ultimately hoping that editing that list will help us past some goofy search results (if not, I'm back with another question). But I can't edit the list if I can't even find it. What am I missing? Someone please put me on the right path to find the list of stopwords. (I'm using Koha version 3.01.00.061, if that makes a difference.) Thanks much! Kurt A.
