Search Technologies
There are three main technologies that are used by edX:
- Elasticsearch - https://github.com/elastic/elasticsearch
- Haystack - http://haystacksearch.org/
- This library simplifies the process of indexing and searching Django models
- Note: it is not designed for use with Mongo (see the Haystack FAQ)
- edX Search - https://github.com/edx/edx-search
- This is a home grown library on top of Elasticsearch
- It was implemented in order to support searching across the courseware Mongo database
- Notes on search implementation
We are currently stuck on an old version of Elasticsearch because of a Forum's Ruby library that can't be upgraded. See:
