Welcome to Haystack!
Haystack provides modular search for Django. It features a unified, familiar API that allows you to plug in different search backends (such as Solr, Elasticsearch, Whoosh, Xapian, etc.) without having to modify your code.

Haystack has a relatively easily-met set of requirements.
- Python 2.7+ or Python 3.3+
- A supported version of Django: https://www.djangoproject.com/download/#supported-versions
Additionally, each backend has its own requirements. You should refer to :doc:`installing_search_engines` for more details.
