elasticsearch中文分詞

默認的中文分詞，是將中文拆分成每一個字,這樣拆分是個很糟糕的事情

---

---

 

get  _analyze 
{
  "analyzer":"ik_max_word",
  "text":"高中化學不等式" 
}

 

---

get  _analyze 
{
  "analyzer":"ik_smart",
  "text":"高中化學不等式" 
}

---

此時，引入中文分詞器

---

使用winscp工具將elasticsearch-analysis-ik6.rar解壓後的文件夾analysis-ik 拷貝到elasticsearch-6.3.1/plugins目錄下

---

 

 

---

然後啓動elasticsearch，緊接着啓動kibana
