检索数据

请求:GET 127.0.0.1:9200/books/novel/1(1为id的值)
返回值

{
    "_index": "books",
    "_type": "novel",
    "_id": "1",
    "_version": 1,
    "found": true,
    "_source": {
        "author": "朱林",
        "price": "79.00",

类型(type)全部检索(条件查询):GET 127.0.0.1:9200/books/novel/_search

模糊匹配查询

请求:`GET 127.0.0.1:9200/books/novel/_search
参数

    {
    "query":{
        "match":{
            "bookname":"价值"
        }
    }
}

但是这个查询会将会将"价值"分词,所以含"价"和"值"的数据都会被查出来,而我们希望含"价值"这个词语的数据被查询出来,因此用习语匹配查询(短语搜索)

习语匹配查询(短语搜索)

请求:`GET 127.0.0.1:9200/books/novel/_search
参数

    {
    "query":{
        "match_phrase":{
            "bookname":"价值"
        }
    }
}
