============用"保溫杯"分詞後的結果===============

GET tongyiciv2/_analyze { "text": "保溫杯", "analyzer": "ik_sync_smart" }

{

"tokens" : [
{
"token" : "保溫杯",
"start_offset" : 0,
"end_offset" : 3,
"type" : "CN_WORD",
"position" : 0
},
{
"token" : "杯子",
"start_offset" : 0,
"end_offset" : 3,
"type" : "SYNONYM",
"position" : 0
}
]
}

============用"杯子"分詞後的結果===============

GET tongyiciv2/_analyze
{
"text": "杯子",
"analyzer": "ik_sync_smart"
}

{
"tokens" : [
{
"token" : "杯子",
"start_offset" : 0,
"end_offset" : 2,
"type" : "CN_WORD",
"position" : 0
},
{
"token" : "保溫杯",
"start_offset" : 0,
"end_offset" : 2,
"type" : "SYNONYM",

]
}

===========用"杯子"查詢=================

GET tongyiciv2/_search
{
  "query": {
    "match": {
      "goodsName": "杯子"
    }
  }
}

===========用"保溫杯"查詢=================
GET tongyiciv2/_search
{
  "query": {
    "match": {
      "goodsName": "保溫杯"

"successful" : 5,
"skipped" : 0,

注意:

我是在本地測試,在配置或者刪除同義詞時要重啟es 伺服器 bin/.elasticsearch

同義詞配置有兩種:

1,a=>b: 通俗的來講,就是儘管使用者輸入的是a,但是es在查詢的是會轉成b去搜索,比如 保溫杯=>杯子,使用者輸入的是"保溫杯",但是es會用"杯子"去做搜尋

2,a,b:通俗的來講,就是不管使用者輸入的是a還是b,es在查詢的是用a,或者b搜尋.比如 保溫杯,杯子,使用者輸入的是"保溫杯",es會用"杯子"去做搜尋,也會用"保溫杯"搜尋
