Percolate没有按预期返回结果

Question

我们正在尝试设置和使用渗透,但我们并没有像预期的那样得到结果.

首先,我注册了几个问题:

curl -XPUT 'localhost:9200/index-234234/.percolator/query1' -d '{
    "query" : {
        "range" : {
            "price" : { "gte": 100 }
        }
    }
}'

curl -XPUT 'localhost:9200/index-234234/.percolator/query2' -d '{
    "query" : {
        "range" : {
            "price" : { "gte": 200 }
        }
    }
}'

然后,当我尝试将它与150匹配时,理想情况下只匹配query1,而不是匹配两个查询:

curl -XGET 'localhost:9200/index-234234/message/_percolate' -d '{
    "doc" : {
        "price" : 150
    }
}'

{"took":4,"_shards":{"total":5,"successful":5,"failed":0},"total":2,"matches":[{"_index":"index-234234","_id":"query1"},{"_index":"index-234234","_id":"query2"}]}

关于为什么会发生这种情况的任何指示都将非常感激.

Answer 1

问题是您在设置文档的映射之前注册了过滤器查询.过滤器必须在没有定义映射的情况下注册查询,这对于范围查询尤其是一个问题.

您应该通过删除索引重新开始,然后首先运行此映射命令:

curl -XPOST localhost:9200/index-234234 -d '{
 "mappings" : {
      "message" : {
        "properties" : {
          "price" : {
            "type" : "long"
          }
        }
      }
    }
}'

然后执行以前的命令(注册两个过滤器查询,然后渗透一个文档),您将得到以下正确的响应:

{"took":3,"_shards":{"total":5,"successful":5,"failed":0},"total":1,"matches":[{"_index":"index-234234","_id":"query1"}]}

您可能会发现几年前的讨论很有帮助:
