Hi!
Our index has a join field (parent documents with many child items). We would like to make a search on child items, with a filter that use some information from the parent document.
Is it possible to access parent fields in the filter script? If so, how can we do it? Would it need a recent version of ES?
Thanks!
Parnt/child documents are not accessible to each other, as they are separate Lucene documents. Take a look at the has parent query. From there you can filter which children match based on the respective parent.
