Filter Search Results on Syntex Confidence Score

I am using SharePoint Syntex and was trying to create a custom PnP search results page but want it to exclude any document with a score under 99%. I can't seem to get it to work.

Tried....

• PrimeConfidenceScore:range(99.00, max)
• PrimeConfidenceScore:99*
• PrimeConfidenceScore>=99
