前面簡單的使用過term查詢過，這里進行加深的學習。
1.說明
單詞級別查詢 這些查詢通常⽤於結構化的數據，⽐如：number, date, keyword等，⽽不是對text。
也就是說，全⽂本查詢之前要先對⽂本內容進⾏分詞，⽽單詞級別的查詢直接在相應字段的
反向索引中精確查找，單詞級別的查詢⼀般⽤於數值、⽇期等類型的字段上
2.准備數據
刪除索引
添加索引
批量導入數據
DELETE /nba
PUT /nba
{
"mappings": {
"properties": {
"birthDay": {
"type": "date"
},
"birthDayStr": {
"type": "keyword"
},

"teamName": {
"type": "keyword"
},
"teamNameEn": {
"type": "keyword"
},
"weight": {
"type": "text"
}
}
}
}
3.Term query 精准匹配查詢(查找號碼為23的球員)
POST nba/_search
{
"query": {
"term": {
"jerseyNo": "23"
}
}
}
4.Exsit Query 在特定的字段中查找⾮空值的⽂檔(查找隊名⾮空的球員)
POST nba/_search
{
"query": {
"exists": {
"field": "teamNameEn"
}
}
}
5.Prefix Query 查找包含帶有指定前綴term的⽂檔(查找隊名以Rock開頭的球員)
POST nba/_search
{
"query": {
"prefix": {
"teamNameEn": "Rock"
}
}
}
6.Wildcard Query ⽀持通配符查詢，*表示任意字符，?表示任意單個字符(查找⽕箭隊的球員)
POST nba/_search
{
"query": {
"wildcard": {
"teamNameEn": "Ro*s"
}
}
}
7.Regexp Query 正則表達式查詢(查找⽕箭隊的球員)
POST nba/_search
{
"query": {
"regexp": {
"teamNameEn": "Ro.*s"
}
}
}
8.Ids Query(查找id為1和2的球員)
POST nba/_search
{
"query": {
"ids": {
"values": [1, 2]
}
}
}
