I have a doc like this { title:'', distr\_sentiment:[ {k:"key1", v:"value1"}, {k:"key2", v:"value2"} ] } I want to set distr\_sentiment.k and distr\_sentiment.v doc\_values=true, But I got an error with this message "MergeMappingException[Merge failed with failures {[mapper [distr\_sentiment.v] has different doc\_values values, mapper [distr\_sentiment.k] has different doc\_values values]}]", How can I use doc\_values in array of docs? Oh what can I do to reduce the memory useage on sorting and aggs on this fields? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi, I believe you are trying to enable doc\_values on an existing index? Unfortunately, it cannot be added on the fly and needs to be configured at index creation time (which means you will need to reindex if you already have some data indexed).
