现在是现有的分析仪：
"analyzer": {
"xmap_analyzer": {
"type": "custom",
"char_filter": [ "html_strip"],
"filter": [ "lowercase"],
"tokenizer": "standard"
}
}
我想删除“过滤器”，它将是这样的：
"analyzer": {
"xmap_analyzer": {
"type": "custom",
"char_filter": [ "html_strip"],
"tokenizer": "standard"
}
}
我尝试更新设置，如下所示： https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-update-settings.html#update-settings-analysis
但它无效，我该怎么办？
