Question

我在得到同義詞使用Nest API在彈性工作真正的麻煩在Elasticsearch使用同義詞。

我建立了我的索引和所有適當的設置，但是當我查詢基於一個術語，應該是一個代名詞，因爲如果他們沒有在所有應用的結果出現。這裏是我的設置：

m_objNode = new Uri(Properties.Settings.Default.strLocalElasticSearchURL); 
m_objConnectionSettings = new ConnectionSettings(m_objNode, defaultIndex: "myIndex"); 
m_objElasticClient = new ElasticClient(m_objConnectionSettings); 

IndexSettings indexSettings = new IndexSettings(); 
indexSettings.NumberOfReplicas = 1; 
indexSettings.NumberOfShards = 1; 

CustomAnalyzer exclamation = new CustomAnalyzer(); 
exclamation.Tokenizer = "exclamationTokenizer"; 

indexSettings.Analysis.Tokenizers.Add("exclamationTokenizer", new PatternTokenizer { 
    Pattern = @"!" 
}); 

indexSettings.Analysis.Analyzers.Add("exclamation", exclamation); 
indexSettings.Analysis.TokenFilters.Add("synonym", new SynonymTokenFilter { Synonyms = new[] { "tire => tyre", "aluminum => aluminium" }, IgnoreCase = true, Tokenizer = "whitespace" }); 

m_objElasticClient.CreateIndex(c => c 
    .Index("myIndex") 
    .InitializeUsing(indexSettings) 
    .AddMapping<myClass>(m => m 
     .MapFromAttributes() 
     .IndexAnalyzer("english") 
     .SearchAnalyzer("english")        
     )); 

而且對象我索引是這樣的：

[ElasticType(IdProperty = "JAUniqueKey")] 
public class myClass { 

    public string JAUniqueKey { get; set; } 
    public int JAItemID { get; set; } 
    public string JATitle { get; set; } 
    public string JABody { get; set; } 
} 

我試圖讓場JATitle和JABody與同義詞對齊。

任何想法當然會受到歡迎。

你已經正確創建令牌過濾器，但你沒把它添加到過濾器自定義分析。

IndexSettings indexSettings = new IndexSettings(); 
indexSettings.NumberOfReplicas = 1; 
indexSettings.NumberOfShards = 1; 

CustomAnalyzer exclamation = new CustomAnalyzer(); 
exclamation.Tokenizer = "exclamationTokenizer"; 
exclamation.Filter = new List<string> {"synonym"}; 
indexSettings.Analysis.Tokenizers.Add("exclamationTokenizer", new PatternTokenizer 
{ 
}); 

indexSettings.Analysis.Analyzers.Add("exclamation", exclamation); 
indexSettings.Analysis.TokenFilters.Add("synonym", new SynonymTokenFilter { Synonyms = new[] { "tire => tyre", "aluminum => aluminium" }, IgnoreCase = true, Tokenizer = "whitespace" }); 

希望它有幫助。
