nest - 在 Elasticsearch.net、Nest 上使用 Stop Filter 和 stopword_path

Question

我如何将停止过滤器...与stopword_path一起使用？ 我可以在 postman 中使用停止过滤器

这是我的代码。

    "analysis" : {
    "analyzer" : {
        "ilhee_Custom" : {
            "type": "custom",
                "tokenizer" : "whitespace",
                "filter" : ["lowercase", "my_stoplist"]
                 }
            },
    "filter" : {
         "my_stoplist" : {
            "type" : "stop",
                "stopwords_path" : "stopword_list.txt",
                    "remove_trailing" : true
                    }
                }
            }
    }

我找到答案了!!是吗？

     var stoplist = new StopTokenFilterDescriptor();
        stoplist.StopWordsPath(@"\stopword_list.txt");   
       var createIndexResponse = client.CreateIndex("ilhee", c => c
        .Settings(s => s
         .Analysis(a => a
          .Analyzers(ad => ad       
           // give the custom analyzer a name
           .Custom("ilhee_Custom", ca => ca
            .Tokenizer("standard")
            .Filters("lowercase", "stop", "standard", "snowball","my_stoplist")
           )
          )
          .TokenFilters(s1=>s1
          .UserDefined("my_stoplist",stoplist))
            )       
         )
    );

Answer 1

那会起作用的。您还可以使用 TokenFiltersDescriptor

上的 Stop() 方法

var createIndexResponse = client.CreateIndex("ilhee", c => c
    .Settings(s => s
        .Analysis(a => a
            .Analyzers(ad => ad
                // give the custom analyzer a name
                .Custom("ilhee_Custom", ca => ca
                    .Tokenizer("standard")
                    .Filters("lowercase", "stop", "standard", "snowball", "my_stoplist")
                )
            )
            .TokenFilters(s1 => s1
                .Stop("my_stoplist", tf => tf
                    .StopWordsPath("stopword_list.txt")
                )
            )
        )   
    )
);

Path is relative to config location or an absolute path.
