Re: Parent/Child (Nested Document) Faceting

Last addition, in the case of multi-level hierarchy. I think I found what we can not reproduce : *json.facet*={ top_reviewers: { type: terms, field: author_s, facet: { reviewCount: "unique(parent_s)", facet: { type: terms,

Re: Parent/Child (Nested Document) Faceting

Alessandro, > facet: {booksCount:"unique(_root_)"} is a pretty cool finding. it's what literally Elastic does in "reverse-nested-aggregation". it's interesting how much it costs for shards. I'll look deeper. Thanks, Alessandro! Yonik, JSON Facets rocks! On Thu, Nov 12, 2015 at 1:25 PM,

Re: Parent/Child (Nested Document) Faceting

Hi Mikhail, how about this : json.facet={ top_reviewers: { type: terms, field: author_s, sort: "booksCount desc", facet: { booksCount: "unique(_root_)" } } } We query on children ( comments) and we calculate that facets. This should

Re: Parent/Child (Nested Document) Faceting

I was experimenting with multi-level hierarchy of nested objects. the _root_ field will always point to the root parent id. If I model Books - Reviews - Comments , where do I have the reference to the parent ? I think we are getting closer to the understanding of the ES functionality. It should

Re: Parent/Child (Nested Document) Faceting

Adding to Yonik response, I think the feature shown by the Elastic Search blog is simply the "Faceting on Parents" one, "A special single bucket aggregation that enables aggregating on parent docs from nested documents. " Indeed it seems to not search on the parents then facets on children and

I found that example has not enough data to reproduce this functionality. what if Mary left the same comment to the same book (book2_c4), then we search for th* across comments http://localhost:8983/solr/techproducts/select?q=comment_t%3Ath*=csv=true=author_s,comment_t,id and get

Parent/Child (Nested Document) Faceting

Hey Folks, I'd love some feedback on the interface for nested document faceting (or rather switching facet domains to/from parent/child). See the bottom of this blog: http://yonik.com/solr-nested-objects/ Issue #1: How to specify that one should change domains before faceting? I originally
