    'pgindex',

Usage

Create and Index class and register it to your model, much like registering an admin class to your model. Example:

# models.py
from django.db import models
from .index import ItemIndex
from pgindex import register

class Item(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()

    def get_absolute_url(self):
        return '/item/'

register(Item, ItemIndex)


# index.py
from pgindex import IndexBase, Vector

class ItemIndex(IndexBase):
    def get_description(self):
        return self.obj.content

    def get_data(self):
        return self.obj

    def get_vectors(self):
        return (
            Vector(self.obj.title, weight='A'),
            Vector(self.obj.content, weight='B'),
        )

To search simply use the pgindex.search method which returns a queryset from the pgindex.models.Index model:

from pgindex import search

index_queryset = search('foo')

See tests for examples.
