1. 通过post构建(DSL方式)路径: http://47.107.41.60:9200/shop/_doc/_search
参数
{ "query":{ "match":{ "desc":"慕课网" } }}查询结果:
{ "took": 9, "timed_out": false, "_shards": { "total": 3, "successful": 3, "skipped": 0, "failed": 0 }, "hits": { "total": { "value": 3, "relation": "eq" }, "max_score": 1.4819028, "hits": [ { "_index": "shop", "_type": "_doc", "_id": "1004", "_score": 1.4819028, "_source": { "id": 1004, "age": 22, "username": "flyfish", "nickname": "水中鱼", "money": 55.8, "desc": "昨天在学校的池塘里，看到有很多鱼在游泳，然后就去慕课网上课了", "sex": 0, "birthday": "1988-02-14", "face": "https://gitee.com/static/images/logo-black.svg?t=158106664" } }, { "_index": "shop", "_type": "_doc", "_id": "1002", "_score": 0.83427787, "_source": { "id": 1003, "age": 20, "username": "bigFace", "nickname": "飞翔的巨鹰", "money": 66.8, "desc": "慕课网团队和导游坐飞机去海外旅游,去了新马泰和欧洲", "sex": 1, "birthday": "1996-01-14", "face": "https://gitee.com/static/images/logo-black.svg?t=158106664" } }, { "_index": "shop", "_type": "_doc", "_id": "1003", "_score": 0.83427787, "_source": { "id": 1003, "age": 20, "username": "bigFace", "nickname": "飞翔的巨鹰", "money": 66.8, "desc": "慕课网团队和导游坐飞机去海外旅游,去了新马泰和欧洲", "sex": 1, "birthday": "1996-01-14", "face": "https://gitee.com/static/images/logo-black.svg?t=158106664" } } ] }}查找某个字段是否存在
查询某个字段
分页
from：0 // 从第0条开始
size:10 // 每页大小
4. 查询关键字term、terms(不分词)
terms允许数组的形式
slop为允许跳过词的数量
operator里可以指明是and还是or，and是分词里的词要都匹配，or是匹配一个就行
多于百分之60将会被检测出来
多于2个将会被匹配出来
提高某个字段的权重boost
eg: 提高nickname字段的权重，可以在字段的后面加上^10
可以组合多重查询
must：查询必须匹配搜索条件，譬如 andshould：查询匹配满足1个以上条件，譬如 ormust_not：不匹配搜索条件，一个都不要满足操作
还可以使用boost进行加权
代表的是检索完成后进行的过滤，效率高，对结果进行过滤，也不会进行分值的计算
range代表范围
gt代表大于
lt代表小于
gte: 大于等于
lte: 小于等于
对text进行排序，会报错，通常我们可以为这个字段增加额外的一个附属属性，类型为keyword，用于做排序。
主属性.keyword
添加highlight，同时可以指定前缀后缀
