How to ignore match on articles like "a" "in" "the" "this"

I don't want the search to match small words that are not related to the content like "on" "in" "this" "and"

Is there a way to do that.

For instance, when someone searches   "inns"    you would expect a hotel to be returned but instead you get everything with the word  "in" 


I may be missing an obvious setting.
