我想检查该字段是否存在于elasticsearch 1.3中，该字段为job_portal_id，请在下面找到我的查询
我也在使用Elasticsearch的php package
array:2 [
"query" => array:1 [
"filtered" => array:2 [
"query" => []
"filter" => array:2 [
"constant_score" => array:1 [
"exists" => array:1 [
"field" => "job_portal_id"
]
]
"term" => array:1 [
"location.country_code" => "ae"
]
]
....
当我运行此查询时，我在查询中获得错误异常
SearchPhaseExecutionException[Failed to execute phase [query], all shards failed; shardFailures
