Hi , In this page - [http://www.elasticsearch.org/guide/reference/mapping/boost-field/](http://www.elasticsearch.org/guide/reference/mapping/boost-field/) I want the boost term to be the field A and if A is null , the value should be B. Is this possible in ES. ~Ban -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
