在pyelasticsearch搜索中指定搜索类型

Question

在使用pyelasticsearch搜索时，有没有办法指定搜索类型？文档中没有关于'scan'，'scroll'，'query_and_fetch‘等的内容。运行以下代码：

from pyelasticsearch import ElasticSearch
es = ElasticSearch(...)

query = {
    "query" : {
        "term" : { "DocContent" : "the" }
    }
}
x = es.search(query, index='main', search_type='scan', scroll='1m')

生成以下错误：

E:\query>python query.py
Traceback (most recent call last):
  File "query.py", line 11, in <module>
    x = es.search(query, index='main', scroll='1m', document_type='scan')
  File "C:\Python27\lib\site-packages\pyelasticsearch-0.7.1-py2.7.egg\pyelasticsearch\client.py", line 96, in decorate
    return func(*args, query_params=query_params, **kwargs)
  File "C:\Python27\lib\site-packages\pyelasticsearch-0.7.1-py2.7.egg\pyelasticsearch\client.py", line 591, in search
    return self._search_or_count('_search', query, **kwargs)
TypeError: _search_or_count() got an unexpected keyword argument 'search_type'

看起来你得到了一个旧的pyleasticsearch库，更新或其他:(
