What if the Elasticsearch ik plug-in can accurately search Chinese?

Aug 04, 2016 am 09:21 AM
elasticsearch laravel php

The following index is generated in Elasticsearch(ik)
The example structure is as follows

<code>      array(5) {
        ["_index"]=>
        string(10) "n_index"
        ["_type"]=>
        string(9) "n_type"
        ["_id"]=>
        string(20) "AVXdrZDVceqO8Q-vidP2"
        ["_score"]=>
        float(0.5171687)
        ["_source"]=>
        array(5) {
          ["id"]=>
          int(111)
          ["title"]=>
          string(82) "北京16款现代300顶级配置"
        }
      }```
      
      
比如我建了好多这样的索引
title字段列表如下
"北京16款现代300顶级配置"
"16款现代300北京顶级配置"
"北京16款起亚顶级配置"
"北京16款300顶级配置"
。。。


如何能实现查询结果返回以下几条


"北京16款现代300顶级配置"
"16款现代300北京顶级配置"</code>

<code>GET /_search

    "query": {
        "match_phrase": {  //match分词搜索命中 match_phrase分词全匹配

Try this structured query

  • List items

  • List items

  • List items

Currently, according to the example of https://github.com/medcl/elasticsearch-analysis-ik, you can find the keywords separated from the word segmentation, but for example, I added curl -XPOST http://localhost:9200/index/fulltext/ 4 -d'
{"content":"The suspect who was shot by an Asian man at the Chinese Consulate in Los Angeles has surrendered"}
'
I want to check this line through "Chinese Man", can this es be achieved? Does it require special configuration or (this configuration in the example cannot be implemented)
