巢狀更新索引設定

Question

我正在關注創建索引嵌套並嘗試更新索引設置的文章。 一切運行正常，但是html_strip過濾器未剝離HTML。 我的代碼是

var node = new Uri(_url + ":" + _port);
var settings = new ConnectionSettings(node);
settings.SetDefaultIndex(index);
_client = new ElasticClient(settings);

//to apply filters during indexing use folding to remove diacritics and html strip to remove html
_client.UpdateSettings(
        f = > f.Analysis(descriptor = > descriptor
                .Analyzers(
                        bases = > bases
                        .Add("folded_word", new CustomAnalyzer
                        {
                        Filter = new List < string > { "icu_folding", "trim" },
                                Tokenizer = "standard"
                        }
                        )
                        )
                .CharFilters(
                        cf = > cf.Add("html_strip", new HtmlStripCharFilter())
                        )
                )
        );

您遇到錯誤：

無法更新非動態設置[[index.analysis.analyzer.folded_word.filter.0，index.analysis.char_filter.html_strip.type，index.analysis.analyzer.folded_word.filter.1，index.analysis.analyzer.folded_word .type，index.analysis.analyzer.folded_word.tokenizer]]用於開放索引[[my_index]]

在嘗試更新設置之前，請先關閉索引，然后再更新設置並重新打開。 看一看。

client.CloseIndex(..);

client.UpdateSettings(..);

client.OpenIndex(..);

更新

將html_strip字符過濾器添加到自定義分析器：

.Analysis(descriptor => descriptor
                    .Analyzers(bases => bases.Add("folded_word",
                        new CustomAnalyzer
                        {
                            Filter = new List<string> { "icu_folding", "trim" }, 
                            Tokenizer = "standard", 
                            CharFilter = new List<string> { "html_strip" }
                        }))
                )

現在，您可以運行測試以檢查此分析器是否返回正確的令牌：

client.Analyze(a => a.Index(indexName).Text("this <a> is a test <div>").Analyzer("folded_word"));

輸出：

this
is
a
test
