Elasticsearch IK 同义词

本文主要是介绍Elasticsearch IK 同义词，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

同义词配置

step 1

elasticserach.yml 最后一行添加：
index.analysis.analyzer.default.type: ik

step 2

在elasticsearch-2.3.1/config目录下面，存放synonyms.txt

其中，synonyms.txt 编码格式为’utf-8’，内容为：

    #Example:ipod, i-pod, i podfoozball , foosballuniverse , cosmos西红柿, 番茄马铃薯, 土豆aa, bb

step 3

新建立索引类型设置

curl -XPUT localhost:9200/test/_mapping?pretty -d '
{"settings": {"index": {"analysis": {"analyzer": {"jt_cn": {"type": "custom","use_smart": "true","tokenizer": "ik_smart","filter": ["jt_tfr","jt_sfr"],"char_filter": ["jt_cfr"]},"ik_smart": {"type": "ik","use_smart": "true"},"ik_max_word": {"type": "ik","use_smart": "false"}},"filter": {"jt_tfr": {"type": "stop","stopwords": [" "]},"jt_sfr": {"type": "synonym","synonyms_path": "synonyms.txt"}},"char_filter": {"jt_cfr": {"type": "mapping","mappings": ["| => \\|"]}}}}},"mappings": {"solution": {"properties": {"title": {"include_in_all": true,"analyzer": "jt_cn","term_vector": "with_positions_offsets","boost": 8,"store": true,"type": "string"}}}}
}
'

step 4

curl -XPUT localhost:9200/test/solution/1 -d '
{"title": "番茄"
}
'
curl -XPUT localhost:9200/test/solution/2 -d '
{"title": "西红柿"
}
'

step 5

  curl -XPOST 'localhost:9200/test/solution/_search?pretty' -d '{"query": {"query_string": {"title": {"query": "西红柿","analyzer": "jt_cn"}}},"highlight": {"pre_tags": ["<tag1>","<tag2>"],"post_tags": ["</tag1>","</tag2>"],"fields": {"title": {}}}}'

step 6

   {"took": 3,"timed_out": false,"_shards": {"total": 5,"successful": 5,"failed": 0},"hits": {"total": 2,"max_score": 0.4500804,"hits": [{"_index": "test","_type": "solution","_id": "1","_score": 0.4500804,"_source": {"title": "西红柿"}},{"_index": "test","_type": "solution","_id": "2","_score": 0.36006433,"_source": {"title": "番茄"}}]}}
