Elasticsearch Engine (preview)

The default Answer uses a built-in database such as MySQL as its search engine. However, when dealing with large amounts of data, the speed and accuracy of searches can be affected. Therefore, we provide a plugin that uses Elasticsearch as the search engine, which greatly improves search speed and accuracy.

How to use

Build

./answer build --with github.com/apache/answer-plugins/search-elasticsearch

Configuration

• Endpoints - Elasticsearch connection address, such as http://127.0.0.1:9200 or multiple addresses separated by ','
• Username - Elasticsearch username
• Password - Elasticsearch password

Note

• Only support Elasticsearch 7.x
• Index name is answer_post. It will create automatically if not exists.
• You also can create index manually if you want to specify search_analyzer or other settings(replicas and shards).
