Lucene查询字符串Elasticsearch"小于或等于"[URI搜索]

Question

在如此多的网站上,他们教授如何使用范围查询从Elasticsearch查询数据.我想使用像这样的Lucene样式查询字符串从Elasticsearch查询小于或等于某个数字的数据.

fieldname:[* TO 100] 

要么

fieldname:["*" TO "100"]

我尝试过其他格式,但没有一种有效.有人能帮我吗？

您将需要使用查询字符串语法(http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-query-string-query.html)范围与URI搜索结合使用(http: //www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-uri-request.html)

范围

可以为日期,数字或字符串字段指定范围.包含范围用方括号[min TO max]和带括号{min TO max}的独占范围指定.

    All days in 2012:

    date:[2012/01/01 TO 2012/12/31]

    Numbers 1..5

    count:[1 TO 5]

    Tags between alpha and omega, excluding alpha and omega:

    tag:{alpha TO omega}

    Numbers from 10 upwards

    count:[10 TO *]

    Dates before 2012

    date:{* TO 2012/01/01}

Curly and square brackets can be combined:

    Numbers from 1 up to but not including 5

    count:[1..5}

Ranges with one side unbounded can use the following syntax:

age:>10
age:>=10
age:<10
age:<=10

Note

To combine an upper and lower bound with the simplified syntax, you would need to join two clauses with an AND operator:

age:(>=10 AND < 20)
age:(+>=10 +<20)

The parsing of ranges in query strings can be complex and error prone. It is much more reliable to use an explicit range filter.

URI搜索

搜索URI搜索请求正文搜索搜索Shards API搜索模板构面聚合建议者上下文建议者多搜索API计数API验证API解释API过滤器更像此API基准

可以通过提供请求参数纯粹使用URI来执行搜索请求.使用此模式执行搜索时,并非所有搜索选项都会暴露,但它可以方便快速"卷曲测试".这是一个例子:

$ curl -XGET
'http://localhost:9200/twitter/tweet/_search?q=user:kimchy'

我想你想查询小于等于100的文档。

 curl -XPOST "http://hostname:9200/index/try/_search" -d'
{
 "query": {
    "range": {
      "FieldName": {
         "lte" : 100
      }
    }
  }
}'

PHP API 客户端

array(
'query' => array(
    'range' => array(
        'FieldName' => array(
            array("lte" => 100)
        )
    )
  )
);
