Question

我有一个名为用户的索引

当我通过以下查询在http://localhost:9200/users/_search?pretty=true上发出请求时：

curl -X GET "localhost:9200/users/_search?pretty=true" -H 'Content-Type: application/json' -d'
{
"query": {
    "query_string": {
    "query" : "firstName: Daulet"
}
}
}'

查询返回两个具有以下名称的用户：

firstName: Daulet

firstName: Daulet Nurlanuly

如何使查询字符串查询以firstName: Daulet返回文档？

我已经发现Elasticsearch使用Apache Lucene的请求语法，对于严格的搜索，我需要通过将请求括在引号中来执行以下操作：

firstName: "Daulet"

但是它已经包含在引号中

仅使用查询字符串查询该怎么做？

**更新**

我在http://localhost:9200/users发出GET请求时得到的响应：

您是正确的，需要用双引号将值引起来。您走在正确的道路上，只需要转义双引号并使用firstName.keyword字段而不是firstName即可，基本上是这样的：

curl -X GET "localhost:9200/users/_search?pretty=true" -H 'Content-Type: application/json' -d'
{
"query": {
    "query_string": {
    "query" : "firstName.keyword:\"Daulet\""
}
}
}'
