Elasticsearch : Query string on field

Question

有人可以告诉我检查标题字段是否包含项目是对还是错

curl -XGET "http://localhost:9200/myapp/item/_search" -d'
{
    "query": {
        "query_string": { 
           "query": "title:Item"
        }
    }
}'

编辑

我有一个像“经济学和统计学”这样的标题

这个返回一条记录

curl -XGET "http://localhost:9200/myapp/item/_search" -d'
{
    "query": {
        "query_string": { 
           "query": "title:*statistics*"
        }
    }
}'

这个不返回任何东西

curl -XGET "http://localhost:9200/myapp/item/_search" -d'
{
    "query": {
        "query_string": { 
           "query": "title:statistics"
        }
    }
}'

这个也不返回任何东西(奇怪)

curl -XGET "http://localhost:9200/myapp/item/_search" -d'
{
    "query": {
        "query_string": { 
           "query": "title:*Economics*"
        }
    }
}'

文档说:

状态字段包含 active

status:active

Answer 1

you can mention a particular field in default_field

{
    "query_string" : {
        "default_field" : "content",
        "query" : "this AND that OR thus"
    }
}

if you want to specify more than one field then 

{
    "query_string" : {
        "fields" : ["content", "name"],
        "query" : "this AND that"
    }
}
