I came across this web part "Random Document". It worked fine for one of my requirements. However, now what I want it to select some n rows of n categories.

For example if I have 13 Species, I want it to return 13 rows, 1 of each specie. Can I somehow get this?

ANy alternative way to write this?

I wrote some query. However, though it is returning 1 doc of each specie, but it is returning same set of docs everytime

Any help!!
