我已经下载了包含技能分类法的 onet 数据集,并将其上传到弹性搜索中。在技能分类中,有一些技能,如 c++、.net、C#。我想给 c# 并且只获得 c# 的技能。通过检查一些链接,我将索引的映射和设置设置如下。

当我使用如下查询时
{
"query": {
"bool": {
"must": [
{
"match": {
"Skill": "c++"
}
}
]
}
},
"size": 10
我正在获得所有具有“c”的技能
当我使用如下查询时假设应用了分析器
{
"query": {
"bool": {
"must": [
{
"match": {
"Skill.analyzed": "c++"
}
}
]
}
},
"size": 10
}
我得到空输出。我是否正确包含了分析器,还是我的查询错误?
