How can I create an index with pymongo
提问by Maximilian
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:
我想在我的 Mongo DB 中的特定字段启用文本搜索。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：
db.foo.ensure_index(('field_i_want_to_index', 'text'), name="search_index")
I get the following error message:
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
Is there a different/better way to create an index in pymongo?

Use the create_indexmethod where you pass in the keys as an array and TEXTas the index direction :
使用将create_index键作为数组和TEXT索引方向传递的方法：
collection.create_index([('field_i_want_to_index', pymongo.TEXT)], name='search_index', default_language='english')
