如何使用 pymongo 创建索引 [英] How can I create an index with pymongo

问题描述

我想在我的 Mongo 数据库中的特定字段中启用文本搜索.我想在 python (-> pymongo) 中实现这个搜索.当我按照互联网上的说明进行操作时:

I want to enable text-search at a specific field in my Mongo DB. I want to implement this search in python (-> pymongo). When I follow the instructions given in the internet:

db.foo.ensure_index(('field_i_want_to_index', 'text'), name="search_index")

我收到以下错误消息:

    Traceback (most recent call last):
    File "CVE_search.py", line 8, in <module>
    db.foo.ensure_index(('field_i_want_to_index', 'text'), name="search_index")
 File "/usr/local/lib/python2.7/dist-packages/pymongo/collection.py", line 1599, in ensure_index
        return self.create_index(key_or_list, cache_for, **kwargs)
      File "/usr/local/lib/python2.7/dist-packages/pymongo/collection.py", line 1466, in create_index
        index_doc = helpers._index_document(keys)
      File "/usr/local/lib/python2.7/dist-packages/pymongo/helpers.py", line 100, in _index_document
            for (key, value) in index_list:
    ValueError: too many values to unpack

是否有不同/更好的方法在 pymongo 中创建索引?

Is there a different/better way to create an index in pymongo?

推荐答案

使用 create_index 方法，您可以将键作为数组和 TEXT 作为索引方向:

Use the create_index method where you pass in the keys as an array and TEXT as the index direction :

collection.create_index([('field_i_want_to_index', pymongo.TEXT)], name='search_index', default_language='english')
