Edit the settings.py file of your project and add django.contrib.postgres to the INSTALLED_APPS setting, as follows:
INSTALLED_APPS = [ # ... 'django.contrib.postgres',]
Now, you can search against a single field using the search QuerySet lookup, like this:
from blog.models import PostPost.objects.filter(body__search='django')
This query uses PostgreSQL to create a search vector for the body field and a search query from the term django. Results are obtained by matching the query with the vector.
