初始化
开始操作之前先确定数据库是否已经创建测试template和index,如有直接删除.
- 删除template
curl -XDELETE -u elastic:uates12345 'http://localhost:9200/_template/trade_test_0'
- 删除index
curl -XDELETE -u elastic:uates12345 'http://localhost:9200/trade-test_1'
创建template和index
- 创建template
curl -u elastic:uates12345 -H "Content-Type:application/json" -XPUT http://localhost:9200/_template/trade_test_0 -d ' {
"template": "trade-test_*",
"order": 0,
"settings": {
"analysis": {
"filter": {
"sp_no_ngram_filter": {
"type": "ngram",
"min_gram": 1,
"max_gram": 30
}
},
"analyzer": {
"sp_str_analyzer": {
"type": "custom",
"tokenizer": "standard",
"filter": [

}
}
}
},

"smallRegionId": {
"type": "keyword"
},
"serialNumber": {
"analyzer": "sp_str_analyzer",

}
}
}
}
}'
- 创建索引
curl -XPUT -u elastic:uates12345 'http://localhost:9200/trade-test_1'
添加数据
- 添加数据
curl -u elastic:uates12345 -H "Content-Type:application/json" -XPOST http://localhost:9200/trade_test_0/type -d' {
"orderType": "1",
"smallRegionId": "1213",
"serialNumber": "我爱我的祖国"
}'
分词测试
curl -u elastic:uates12345 -H "Content-Type:application/json" -XPOST http://localhost:9200/trade-test_1/_analyze -d' {

}
}
],
"must_not": [],
"should": []
}
},
"from": 0,
"size": 10,
"sort": [],
"aggs": {}
}'
- match_phrase测试
