Styles with plus (+) show up in the Styles dropdown, but they are not "real" styles - they are not part of the searchable Styles collection. They are (sort of) temporary styles. Word puts them into the Styles dropdown (something I have always hated) when a manual format is made. A good reason to NEVER make manual formatting.

In other words, you can not use Find to find them.

That being said, you could search for a Body style, and THEN test to see if there is a left indent of 0.89.
