Question

我在ElasticSearch中尝试multi_match查询，但查询没有返回任何结果。查询是：

curl -XPOST "http://localhost:9200/smartjn/feed_details/_search" -d'
{
    "query" : {
        "multi_match" : {
            "query" : "Dho*",
            "fields" : [ "title", "wardname" ]
        }
    }
}'
{"took":11,"timed_out":false,"_shards":{"total":5,"successful":5,"failed":0},"hits":{"total":0,"max_score":null,"hits":[]}}

我在以Dho开头的wardname字段中有价值，

{
    _id: ObjectId("56f43c0344fc86e73b1170b0"),
     title: "Constant road work",
     approvalStatus: "approved",
     subward: "56a6124244fc868a255fe3fe",
     wardname: "Dhokali"
    }

不确定为什么不归还任何东西。任何帮助非常感谢。

如果您要搜索以某些字符串开头的内容，则需要使用Phrase Prefix查询。请尝试以下查询。

curl -XPOST "http://localhost:9200/smartjn/feed_details/_search" -d'
{
    "query" : {
        "multi_match" : {
            "query" : "Dho*",
            "fields" : [ "title", "wardname" ],
            "type': 'phrase_prefix"
        }
    }
}'

multi_match查询返回无结果elasticsearch
