I'm not sure how to answer rather than to say "it doesn't", that's not how we parse the word stops.  However, *that's ok*, because `Title:` [isn't what you're *supposed* to use, it's `title:`][1], so this behavior is by-design.  All ninja search options should be lower-case [as the search help page shows][2], those are specifically what we're looking for.
