Haystack

How it works

Haystack is a search API for Django based websites, which allow users to use different search backend as per their choice. Appstore uses Haystack and Whoosh for the backend.

• Haystack has been added to the INSTALLED_APPS tuple in settings/base.py of this repo.

• HAYSTACK_CONNECTIONS is also specified in settings/base.py of this repo. This directs the Haystack to use a particular backend search engine.

• A PATH parameter also needs to be specified in the same script to direct where the index file created by Haystack will be stored for later access while search.

• A url for search via Haystack has been added to urls.py in this repo:

  url(r'^search', include('haystack.urls')),

• The command python manage.py rebuild_index from the base of the project creates the index in folder whoosh_index in the base directory.

• Indexes are saved in the search database in as per the template created in templates/search/indexes/apps/app_text.txt and in templates/search/indexes/apps/author_text.txt

NOTE: Changes to database are NOT reflected until a call to python manage.py rebuild_index The current Appstore addresses this by running a daily cronjob to update the index.
