Yeah the search could use some improvements. The firs result for "pizza" is "Fruit Cookie Pizza" which I think almost no-one searching for pizza will want.
I unfortunately did not find a good field to sort by in the original dataset from earlier today [1]. So it's just sorted by text match relevance scores, and then the order that they appear in the dataset.
I'm hoping they publish a popularity metric, which will fix the issues like the one you pointed out. Or, once I have sufficient data on popular searches from this site, I can append that metric to the dataset.
