Google App Engine Python搜索API文档错误

Question

I'm using the Python 1.6.6 SDK and having trouble getting the search API to initialise a new Document:

from google.appengine.api import search

def index_document(document_id, some_string):
    return search.Document(
        doc_id=document_id,
        fields=[
            search.TextField(name='text_field', value=some_string),
            search.DateField(name='date', value=datetime.now().date())
        ])

In response I get:

AttributeError: type object 'search' has no attribute 'Document'

I can't see any evidence that this is a general problem, and all the docs point to this being the procedure for initialising a Document.

However, if I place the API call within the function it executes as expected:

def index_document(document_id, some_string):

    from google.appengine.api import search

    return search.Document(...

I can't see any reason why this would work, but a global import wouldn't as I am importing a number of their APIs. Has anyone had a similar problem/success in getting it to work?
