Python 2.7 has reached end of support
and will be
deprecated
on January 31, 2026. After deprecation, you won't be able to deploy Python 2.7
applications, even if your organization previously used an organization policy to
re-enable deployments of legacy runtimes. Your existing Python
2.7 applications will continue to run and receive traffic after their
deprecation date. We recommend that
you
migrate to the latest supported version of Python.
The Document Class
Stay organized with collections
Save and categorize content based on your preferences.
Class Document represents a document containing searchable content.
Document is defined in the module google.appengine.api.search.
Constructor
The constructor for class Document is defined as follows:
- class Document(doc_id=None, fields=None, language='en', rank=None)
Construct an instance of class Document.
The following example shows how to create a document consisting of a set of fields, some plain text and one in HTML:
from google.appengine.api import search
search.Document(
doc_id='documentId',
fields=[search.TextField(name='subject', value='going for dinner'),
search.HtmlField(name='body', value='<html>I found a place.</html>'),
search.TextField(name='signature', value='brzydka pogoda', language='pl')],
language='en')
Arguments
- doc_id
The document identifier, a human-readable ASCII string identifying the document. Must contain no whitespace characters and not start with an exclamation point (!). If omitted, the search service will provide an identifier string.
In most cases, you do not need to specify the document identifier explicitly. Specifying your own identifier is useful, however, for implementing search with other storage mechanisms, such as Blobstore or Google Storage. In the case of Blobstore, for example, you can set the document identifier to the BlobKey in order to associate that document with a specific blob.
- fields
An iterable collection of Field objects representing the content of the document.
- language
A two-letter ISO 693-1 code for the language in which the document's field values are expressed.
- rank
The document's rank, an integer specifying the order in which it will be returned in search results. Newer documents are returned first. If not specified the rank will be set to the number of seconds since 1 January 2011 00:00:00 UTC.
Note that when rank is used in a FieldExpression or SortExpression it is referenced as _rank.
Result value
A new instance of class Document.
Exceptions
- TypeError
A parameter has an invalid type or an unknown attribute was passed.
- ValueError
A parameter has an invalid value.
Properties
An instance of class Document has the following properties:
- doc_id
The document identifier, a human-readable ASCII string identifying the document.
- fields
A list of the document's fields.
- language
The two-letter ISO 693-1 code for the language in which the document's field values are expressed.
- rank
The document's rank, an integer specifying the order in which it will be returned in search results.
Note that when rank is used in a FieldExpression or SortExpression it is referenced as _rank.
Also, if you create a SortExpression that includes rank as one of the sort keys, rank can only be sorted in
the DESCENDING direction.
