Not OP, but at a minimum I'd expect range searches to work.
This particular search pattern could either be a open-ended range search "all products 80-infinity" or it could be a keyword search "80+" as in "PSU 80+ Gold".
I'm also noticing that many results have mixed-bag prices, while I was expecting something closer to being ranked by the price delta. For example "psu" returns 5 different $155 products, but "psu 300" returns a $2000 RTX 4090 along with 4 $155 PSU's. I don't know if it's a coincidence that the RTX has a stock of "304" or if you're applying the ranking method to fields outside of price.
