1 介紹
主要介紹索引請(qǐng)求的基礎(chǔ)API操作钙皮，使用postman進(jìn)行請(qǐng)求赁遗，接口請(qǐng)求的前綴地址統(tǒng)一為elasticsearch 部署IP地址+端口號(hào)（例如 http://192.168.51.4:9200 辫愉。
統(tǒng)一請(qǐng)求地址：
POST /search_demo/_doc/_search
2 prefix
prefix 根據(jù)前綴去查詢(xún)栅受，如下示例：
傳遞JSON數(shù)據(jù)
{
"query": {
"prefix": {
"desc": "every"
}
}
}
請(qǐng)求結(jié)果

3 fuzzy
fuzzy 模糊搜索，并不是指的SQL的模糊搜索恭朗，而是用戶在進(jìn)行搜索的時(shí)候打字錯(cuò)誤現(xiàn)象屏镊，搜索引擎會(huì)自動(dòng)糾正，然后嘗試匹配索引庫(kù)中的數(shù)據(jù)痰腮。

"query": {
"multi_match": {
"fields": ["desc","nickname"],
"query": "yuo everyady",
"fuzziness": "AUTO"
}

自動(dòng)糾正數(shù)據(jù)而芥，還是可以查詢(xún)到指定的信息的。
4 wildcard
占位符查詢(xún)膀值。
- ? ：1個(gè)字符
- *： 1個(gè)或者多個(gè)字符
