彈性搜索Python中的批量（輔助）索引錯誤

Question

我正在從Twitter提取數據，進行過濾，制作一個生成器，並嘗試使用助手將大量索引放入Elasticsearch，但是我收到以下錯誤，我似乎無法提取出確切的問題所在。

似乎在許多領域中，elasticsearch似乎在攝取似乎是地理位置數據的問題。 另外，我生成了大約671條我推過的推文，但是當我在彈性搜索中進行計數時，似乎只有454條被索引，此外，我沒有46條文檔推文而失敗，因為地理數據無法顯示確切的位置它是。

這是我用於索引的模板：

這是我用來創建生成器並使用helpers.bulk提取的代碼：

# Global variable
tweet_attributes = ['text','source','retweeted', 'retweet_count','place','lang','favorite_count','entities','id','created_at','user:id','user:screen_name','coordinates']
def _get_necessary_fields(tweets):
    doc = defaultdict(dict)
    fieldInfo = tweet_attributes
    for tweet in tweets:
        for fields in fieldInfo :
            if (len(fields.split(':'))) == 2 :
                keys = fields.split(':')
                # nested array at one level
                doc[keys[0]][keys[1]] = tweet[keys[0]][keys[1]]
                #TODO implement for more than one level, needs better algo
            else:
                # for each field
                if fields in tweet:
                    doc[fields] = tweet[fields]
        yield doc

def _json_for_bulk_body(tweets,el):
    # TODO refactor this code when you have time :
    # http://stackoverflow.com/questions/20288770/how-to-use-bulk-api-to-store-the-keywords-in-es-by-using-python
    structured_json_body = ({
                "_op_type" : "index",
                "_index": el[0],  # index name Twitter
                "_type": el[1][0],  # type is tweet
                "_id": doc['id'],  # id of the tweet
                "_source" :doc} for  doc in _get_necessary_fields(tweets))
    return structured_json_body


    **helpers.bulk(self.es, actions=structured_json_body ,stats_only=True)**

有人可以向我解釋為什么不提取除46個文檔之外的所有文檔，以及為什么不提取46個文檔嗎？

在您的代碼中，您需要檢查該空條件，並且在出現這種情況時不設置字段coordinates

            # for each field
            if fields in tweet:
                if tweet[fields] is not None:                  <--- add this check
                    doc[fields] = tweet[fields]
