Can I search for foods high in a particular nutrient?

I have recently developed a potassium deficiency. My doctor told me to take a prescription potassium tablet for a week. Being that I hate drugs, I started thinking of what foods I could eat more of, that are high in potassium. By now probably we all know that bananas are not really high in potassium, and I found that the highest foods are actually: Tomato products, Orange juice, Beet greens, Beans , dates. But does chronometer offer the opportunity to look at foods that are high in this particular (or any other) nutrient? I could not find this option, and it would certainly be very useful. Thanks!
