I've made some steps ahead. I'm writing a function to this sort of clustered boosting: <str name="bf">product(recip(ms(NOW,data),3.16e-11,1,1),exists(query(field:value)))</str> I multiply the boost, for a specific value of some field, the exists function will return 0 or 1, and this would cancel or use the date boost. But this function I wrote , has a wrong sintax, I need to correct the "exists" part. Any hint?
