Usage

After installing aldryn-search through your package manager of choice, add aldryn_search to your INSTALLED_APPS. If you run a multilingual CMS setup, you have to define a haystack backend for every language in use:

HAYSTACK_CONNECTIONS = {
    'en': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://my-solr-server/solr/my-site-en/',
        'TIMEOUT': 60 * 5,
        'INCLUDE_SPELLING': True,
        'BATCH_SIZE': 100,
    },
    'fr': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': 'http://my-solr-server/solr/my-site-fr/',
        'TIMEOUT': 60 * 5,
        'INCLUDE_SPELLING': True,
        'BATCH_SIZE': 100,
    },
}

To make sure the correct backend is used during search, add aldryn_search.router.LanguageRouter to your HAYSTACK_ROUTERS setting:

HAYSTACK_ROUTERS = ['aldryn_search.router.LanguageRouter',]

When using multiple languages, usually there’s one search backend per language, when indexing it’s important to know which language is currently being used, this can be facilitated by the ALDRYN_SEARCH_LANGUAGE_FROM_ALIAS setting, this setting could be a callable or a string path that resolves to one.

Please keep in mind that it’s usually not a good idea to import things in your settings, however there are cases where it seems overkill to create a function to handle the alias, for example:

ALDRYN_SEARCH_LANGUAGE_FROM_ALIAS = lambda alias: alias.split('-')[-1]

the example above could be used when using multiple languages and sites, all backends could have a language suffix.

The same could be achieved using a function defined somewhere else in your code like so:

ALDRYN_SEARCH_LANGUAGE_FROM_ALIAS = "my_app.helpers.language_from_alias"

If any of the above return None then settings.LANGUAGE_CODE will be used.

By default this setting evaluates to a function that checks if the alias is in settings.LANGUAGES and if so it uses the alias as a language.

For a complete Haystack setup, please refer to their documentation.

Integration with django CMS

aldryn-search comes with an App Hook for django CMS, and a search view using Django’s class based views. If you want to use this app hook, you can either subclass it and register it yourself, or set ALDRYN_SEARCH_REGISTER_APPHOOK to True.

If you want to exclude some cms plugins from indexing, you can specify ALDRYN_SEARCH_PLUGINS_EXCLUDE setting like so:

ALDRYN_SEARCH_EXCLUDED_PLUGINS = [
    "PluginA", "PluginB"
]

For pagination, aldryn-search uses aldryn_common.paginator.DiggPaginator. If you want to use this built-in pagination, make sure to install django-spurl, and add then add spurl to INSTALLED_APPS.
