Thanks so much for your feedback!
Yeah, tuning our search engine a bit is on our list. There's a fine line between setting things too loosely and too tightly. I think right now we have the settings a bit loose.
The Sonus Fabers have the word "opposed" and the Nuprime has "opportunity," so the engine is matching on this. I agree with you, those matches are a bit of a stetch!
The Pioneer has "OPP" listed as as a "Bluetooth Profile" (whatever that means!), so the engine is matched against that as a spell correction.
So great point of feedback! We will take another pass at tuning our search engine to be a bit more granular.
