1 介绍
主要介绍索引请求的基础API操作，使用postman进行请求，接口请求的前缀地址统一为elasticsearch 部署IP地址+端口号（例如 http://192.168.51.4:9200 。
统一请求地址：
POST /search_demo/_doc/_search
2 prefix
prefix 根据前缀去查询，如下示例：
传递JSON数据
{
"query": {
"prefix": {
"desc": "every"
}
}
}
请求结果
{
"took": 11,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "search_demo",
"_type": "_doc",
"_id": "1010",
"_score": 1.0,
"_source": {
"id": 1010,
"age": 30,
"username": "cc",
"nickname": "cc",
"money": 100.8,
"desc": " i cc you everyday",
"sex": 1,
"birthday": "1988-07-14",
"face": "http://www.p2pi.cn/static/img/1010_face.png"
}
}
]
}
}
3 fuzzy
fuzzy 模糊搜索，并不是指的SQL的模糊搜索，而是用户在进行搜索的时候打字错误现象，搜索引擎会自动纠正，然后尝试匹配索引库中的数据。
官方地址：
https://www.elastic.co/guide/en/elasticsearch/guide/current/fuzzy-match-query.html
传递JSON数据
{
"query": {
"multi_match": {
"fields": ["desc","nickname"],
"query": "yuo everyady",
"fuzziness": "AUTO"
}
}
}
请求结果
{
"took": 35,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 4.5765147,
"hits": [
{
"_index": "search_demo",
"_type": "_doc",
"_id": "1010",
"_score": 4.5765147,
"_source": {
"id": 1010,
"age": 30,
"username": "cc",
"nickname": "cc",
"money": 100.8,
"desc": " i cc you everyday",
"sex": 1,
"birthday": "1988-07-14",
"face": "http://www.p2pi.cn/static/img/1010_face.png"
}
}
]
}
}
自动纠正数据，还是可以查询到指定的信息的。
4 wildcard
占位符查询。
- ? ：1个字符
- *： 1个或者多个字符
官网地址：
https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wildcard-query.html
传递JSON数据
{
"query": {
"wildcard": {
"desc": "好*"
}
}
}
请求结果
{
"took": 4,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 3,
"relation": "eq"
},
"max_score": 1.0,
"hits": [
{
"_index": "search_demo",
