I have filtered query with 3 filters - "query": "iphone", color:5, category:10, brand:25 How can i get amount of products in each brand which have color:5 and category:10? In Solr i did it like: facet.field={!ex=tag\_facet\_brand}facet\_brand How can i exclude 1 filter from aggregation context? (i can't use global, because i loose query:iphone, i can't use post\_filter - because of performance) -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
