JR-WordPress on "[Plugin: Relevanssi - A Better Search] Results Order"

Hi,

All of my post's titles start with Paragraph and Paragraph#.
When I search for instance Paragraph 4 or "Paragraph 4" I don't get paragraph 4 as the 1st result.

My minimum word length to index is set for: 1

P.S. When I search for paragraph with 2 digits number I get it as 1st result.

Thank you.
