如何更新弹性搜索指标

Question

我使用csv文件中的logstash将数据添加到了弹性搜索索引中。 我对csv进行了一些更改，现在希望将其反映在弹性索引上。

我该怎么做？

我曾经用Logstash Cofig更新数据以建立索引。

    input{
        file{
        path => "/Users/apple/Desktop/data/gkdata.csv"
        start_position =>"beginning"

        }
    }
    filter{
        csv{
        separator => ","
        columns => ["Index", "Category",    "Sub category", "Sub Sub Category", "Products", "Measure", "Price", "Description",  "Gst"]
        }
        mutate{convert => ["Index", "float"] }
        mutate{convert => ["Price", "float"] }
        mutate{convert => ["Gst", "float"] }
    }
    output{
        elasticsearch{
            hosts => "host"
            user => "elastic"
            password => "xyz"
            index => "gkdb"
            }

    }

我使用此命令将数据上传到我的索引

bin/logstash -f /Users/apple/Desktop/data/logstash_db.config
