if you're not finding anything via search by example you're using it wrong. You'd definitely get some match. See here for instructions:
https://github.com/citation-style-editor/csl-editor/wiki/User-guide-for-the-CSL-Editor
the key part is that you need to use the citation data in the box on the left. You can't just paste any citation you want.

HI Adam,
I figured it out (thanks for the comments). I am editing in the visual CSL editor. I have a question how do I change the spaces between the authors name and the year of the pub? Thanks!

Here it is:

My problem is that there is a paragraph separation between the authors and the year of the pub.

Done. Thanks!
