usage

If you just want to store really simple things, like strings:

engine = RedisEngine()
titles = ['python programming', 'programming c', 'unit testing python',
          'testing software', 'software design']
map(engine.store, titles)

>>> engine.search('pyt')
['python programming', 'unit testing python']

>>> engine.search('test')
['testing software', 'unit testing python']

If you want to store more complex data, like blog entries:

Entry.create(title='an entry about python', published=True)
Entry.create(title='all about redis', published=True)
Entry.create(title='using redis with python', published=False)

for entry in Entry.select():
    engine.store_json(entry.id, entry.title, {
        'published': entry.published,
        'title': entry.title,
        'url': entry.get_absolute_url(),
    })

>>> engine.search_json('pytho')
[{'published': True, 'title': 'an entry about python', 'url': '/blog/1/'},
 {'published': False, 'title': 'using redis with python', 'url': '/blog/3/'}]

# just published entries, please
>>> engine.search_json('redis', filters=[lambda i: i['published'] == True])
[{u'published': True, u'title': u'all about redis', u'url': u'/blog/2/'}]
