The correct name for MongoDB index definition property is weights not weight. Using "weight" will cause "Index with name ... already exists with different options"

Text Search
|
|
===========
|
|
|
|
After MongoDB 2.4 version, supports search documents by text indexes.
|
|
|
|
|
|
Defining a Document with text index
|
|
===================================
|
|
Use the *$* prefix to set a text index, Look the declaration::
|
|
|
|
class News(Document):
|
|
title = StringField()
|
|
content = StringField()
|
|
is_active = BooleanField()
|
|
|
|
meta = {'indexes': [
|
|
{'fields': ['$title', "$content"],
|
|
'default_language': 'english',
|
|
'weights': {'title': 10, 'content': 2}
|
|
}
|
|
]}
|
|
|
|
|
|
|
|
Querying
|
|
========
|
|
|
|
Saving a document::
|
|
|
|
News(title="Using mongodb text search",
|
|
content="Testing text search").save()
|
|
|
|
News(title="MongoEngine 0.9 released",
|
|
content="Various improvements").save()
|
|
|
|
Next, start a text search using :attr:`QuerySet.search_text` method::
|
|
|
|
document = News.objects.search_text('testing').first()
|
|
document.title # may be: "Using mongodb text search"
|
|
|
|
document = News.objects.search_text('released').first()
|
|
document.title # may be: "MongoEngine 0.9 released"
|
|
|
|
|
|
Ordering by text score
|
|
======================
|
|
|
|
::
|
|
|
|
objects = News.objects.search('mongo').order_by('$text_score')
|
