Full text search MongoDB/Mongoengine

Question

The new version of MongoDB allows Full Text Search. That part is running fine for me:

db.collection.runCommand('text',{search:<keyword>})

However, I'm not sure that it is possible to run it through python's mongoengine. Does anyone know if there is a way to run "runCommand" with mongoengine or a workaround?

(I'm using mongoengine for my project, I'd hate to have to drop it for pymongo as it would probably mean recoding many things.)

Thanks!

Answer 1

You can use MongoEngine by using pymongo directly eg:

class MyDoc(Document):
    pass

coll = MyDoc._get_collection()
coll.database.command(
    "text",
    coll.name,
    search="alice", 
    project={"name": 1, "_id": 0}, 
    limit=10)

Answer 2

Pymongo uses keyord arguments for this. See documentation .
In you case db.command('text', 'colection_name', seach='keyword') .

Answer 3

the question is old but I bumped on the same ask. MongoEngine now enables text search directly.

First, create a text index on the required fields:

class MyDoc(Document):
   document_name = StringField()
   document_content = StringField()

   meta = {
      'indexes': [
         {
            'fields': [
               '$document_name',
               '$document_content'
            ]
         }
      ]
   }

Then, documents are searchable using the search_text function:

document = News.objects.search_text('testing')
