我是Elasticsearch的新手。最近一直在探索这一点。
我想从一个表的ElasticSearch中获取所有数据。但在同一时间，我只需要thoose数据，其中“phoneNumber”字段不是一个有效的电话号码。我如何才能做到这一点？
数据结构：

}我想用正则表达式验证数据：/^+？[0-9]{11}$/ ->其中电话号码的长度必须为11，并且可以有前导“+”
以下是我的方法：
const searchFilters = {
query: {
bool: {
must: [],
must_not: [
{
regexp: {
'phoneNumber.keyword': '^\\+?[0-9]{11}$',
},
},
],
filter: [],
},
},
size: 10000,
};
const resp = await ElasticSearchHelper.search(IndexNames.SESSION, searchFilters);
const data = resp.body?.hits?.hits;但它返回空数组数据。我希望有所有的数据，其中电话号码是无效的。

由于elasticsearch的regex运算符支持，您没有任何结果。在文档中提到，elasticsearch正则表达式不支持
^和$。Lucene的正则表达式引擎不支持锚操作符，例如^（行首）或$（行尾）。要匹配一个术语，正则表达式必须匹配整个字符串。
您将需要构建另一个匹配Lucene约束的正则表达式（搜索库elasticsearch就是构建在其上的）

你的方法看起来基本正确，但是在正则表达式和Elasticsearch查询中有几个问题。以下是您可以进行的调整，以使用给定的正则表达式验证数据并检索所需的结果：
1.正则表达式：您提供的正则表达式模式
^+?[0-9]{11}$有一个小错误。+字符需要用反斜杠（\）进行转义，以按字面意思匹配。正确的正则表达式模式是^\+?[0-9]{11}$。regexp查询，而是将must_not子句与term查询一起使用，以实现基于电话号码字段的所需筛选。以下是Elasticsearch查询的更新版本：在
must_not子句中，可以通过设置term查询的value字段来提供要排除的特定无效电话号码。这将获取电话号码字段不等于指定的无效电话号码的所有数据。确保将
IndexNames.SESSION替换为Elasticsearch索引的正确名称。通过这些调整，您应该能够根据定义的正则表达式模式检索电话号码无效的数据。
