Coder, I've verified that this is a bug. However, the "_boost" field will be deprecated in 1.0 in favor of the function_score query (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-function-score-query.html#_using_function_score).
For now, what you can do to fix this is to remove the "_boost" part from your mapping and reindex your data and you should be able to access the "po" field after that. Remove this part from your mapping: "_boost" : { "name" : "po", "null_value" : 4.0 }, -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
