Creating New Backends¶
The process should be fairly simple.
- Create new backend file. Name is important.
- Two classes inside.
- SearchBackend (inherit from haystack.backends.BaseSearchBackend)
- SearchQuery (inherit from haystack.backends.BaseSearchQuery)
Responsible for the actual connection and low-level details of interacting with the backend.
- Connects to search engine
- Method for saving new docs to index
- Method for removing docs from index
- Method for performing the actual query
Responsible for taking structured data about the query and converting it into a backend appropriate format.
- Method for creating the backend specific query -
