ArticleCase缺少巢式省略过滤器? [英] ArticleCase missing from nest elision filter?

问题描述

根据此页上，法语分析器定义为不区分大小写的省略步骤，如下所示:

According to this page, the french analyzer is defined with a case-insensitive elision step like so:

...
"french_elision": {
  "type": "elision",
  "articles_case": true,  // <==== Note this article case property
  "articles": [
    "l", "m", "t", "qu", "n", "s", "j", "d", "c", "jusqu", "quoiqu", "lorsqu", "puisqu"
  ]
},
...

在尝试在NEST(v6.6)中重新创建此代码时，我似乎遇到了一个麻烦，因为似乎不存在ArticleCase调用.只是作为错误而缺失吗?还是应该采用另一种方法?

In trying to recreate this in NEST (v6.6), I seem to have hit a snag in that the ArticleCase call doesn't seem to exist. Is is just missing as a bug? Or is there another way this is supposed to be done?

.Elision("french_elision", f => f
  // .ArticlesCase(true) <==== Doesn't exist
  .Articles("l", "m", "t", "qu", "n", "s", "j", "d", "c", "jusqu", "quoiqu", "lorsqu", "puisqu"))

我还环顾了一下Articles()上的问题，但找不到.我继续运行代码，默认情况下未设置该值.如何确保省略滤波器设置了该值?谢谢

I also looked around for a bool on Articles() or something, but I can't find it. I went ahead and ran the code, and the value is not set by default. How do I make sure the elision filter has this value set? Thanks

推荐答案

在这里可以看到: russcam说以下话:

russcam says the following:

这是丢失的.我们将其添加到下一个版本中.

This is missing. We'll add it into the next release.

同时，您可以通过从ElisionTokenFilter派生来添加它，并添加属性，例如

In the meantime, you can add it by deriving from ElisionTokenFilter and add the property e.g.

public class MyElisionTokenFilter : ElisionTokenFilter 
{
    [PropertyName("articles_case")]
    public bool? ArticlesCase { get; set; }
}

并在您的设置中使用

.UserDefined("french_elision", new MyElisionTokenFilter
{
    ArticlesCase = true,
    Articles = new[] { "l", "m", "t", "qu", "n", "s", "j", "d", "c", "jusqu", "quoiqu", "lorsqu", "puisqu" }
})
