Docker for Elasticsearch with IK Analyzer and Traditional Chinese

It is such a pain to configure IK Analyzer for Traditional Chinese. Thus, this repository provides a properly configured Docker image for Elasticsearch with IK Analysis plugin and Traditional Chinese dictionaries.

The image uses Elasticsearch version 7.16.2.

Usage

docker run --rm -p 9200:9200 -e "discovery.type=single-node" --memory 5G minghsu0107/elasticsearch-chinese:7.16.2

Test Simplified Chinese

create an index:

curl -XPUT http://localhost:9200/index0

curl -XPOST http://localhost:9200/index0/_mapping -H 'Content-Type:application/json' -d'
{
        "properties": {
            "content": {
                "type": "text",
                "analyzer": "ik_max_word",
                "search_analyzer": "ik_smart"
            }
        }
