Blank Spaces in Video Tags

[Boki]

I've been trying to find an answer to this question and it's been bugging me forever.
Are blank spaces important in video tags? That is, is there any tangible difference if I write 'Bible Illustrated' or 'BibleIllustrated'?
I would assume there is, as YouTube recognizes this as two different tags, but I'm curious what you guys think.
Also: I just wrote 'tags' in the 'tags' field below.

Yes, bibleillustrated will be read as one word. Bible illustrated as two or a phrase.
