hit: 索引和文件資訊, 查詢結果總數, 然後就是查詢出來的具體文件

_score 分數我們可以通過來判斷誰更加符合結果

指定查詢結果

GET quanzhan/user/_search
{
  "query": {
    "match": {
       "name": "王"
    }
  },
  "_source": ["name", "desc"] /** 結果過濾 **/

布林值查詢

bool 多條件查詢

must

must 命令(mysql 中的 and), 所有條件都要符合. 比如 where id = 1 and name = xxx

GET quanzhan/user/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "match": {
