我对弹性搜索完全陌生。因此，如果这是一个愚蠢的问题，请原谅我，而我的问题可能已经在其他地方回答了，但我找不到它。 我想将Elastic Search用作网络中PDF和docx的搜索引擎。我使用fscrawler提取PDF以进行弹性搜索。由于我要提取的文档使用多种语言，因此我想使用n-graming来词干。为此，我想像这样更新我的映射
PUT test/_mappings/_all
{
"mappings": {
"title": {
"properties": {
"title": {
"type": "text",
"fields": {
"de": {
"type": "string",
"analyzer": "german"
},
"en": {
"type": "string",
"analyzer": "english"
},
"general": {
"type": "string",
"analyzer": "trigrams"
}
}
}
}
}
}
}
现在我收到此错误消息
{“错误”：{ “根本原因”： [ { “ type”：“ mapper_parsing_exception”， “ reason”：“根映射定义具有不受支持的参数：[映射：{title = {properties = {title = {type = text， 字段= {de = {类型=字符串，分析器=德语}，en = {类型=字符串， Analyzer = english}，general = {type = string，analyzer = trigrams}}}}}}]]“ } ]， “ type”：“ mapper_parsing_exception”， “ reason”：“根映射定义具有不受支持的参数：[映射：{title = {properties = {title = {type = text， 字段= {de = {类型=字符串，分析器=德语}，en = {类型=字符串， Analyzer = english}，general = {type = string，analyzer = trigrams}}}}}}]“”
}，“状态”：400}
您是否知道我该如何解决？还是您有一个主意，如何在不使用fscrawler的情况下提取具有正确映射的文件？
