A third finding nothing is a lot more then I thought.
I was wrong on that one. In your case the titles alone won't catch it, because people type the Latin names and the typos and I can't put "anubia" in a product title without looking silly.
So fine, try Optimi search.
But I'd still rename the top five or ten plants the same week, the ones people mail you about most. It costs one evening and it helps whatever search you end up with.
On my shop I did the renaming only after six months of lost sales, don't wait that long !
