Note that [`KeywordAnalyzer`](https://github.com/apache/lucenenet/blob/7cfc4c340c384bd5af39f42d7591dbe45344fd24/src/Lucene.Net.Analysis.Common/Analysis/Core/KeywordAnalyzer.cs)/[`KeywordTokenizer`](https://github.com/apache/lucenenet/blob/7cfc4c340c384bd5af39f42d7591dbe45344fd24/src/Lucene.Net.Analysis.Common/Analysis/Core/KeywordTokenizer.cs) are suitable for the purpose of not splitting apart values like this. You can use `PerFieldAnalyzerWrapper` in a custom analyzer to specify that the `name` field will use `KeywordAnalyzer` while all other fields will use `StandardAnalyzer`. ```c# using Lucene.Net.Analysis; using Lucene.Net.Analysis.Core; using Lucene.Net.Analysis.Standard; public class CustomAnalyzer : Analyzer { private readonly Analyzer _defaultAnalyzer; private readonly PerFieldAnalyzerWrapper _perFieldAnalyzerWrapper; public CustomAnalyzer() { // Default analyzer for most fields _defaultAnalyzer = new StandardAnalyzer(Lucene.Net.Util.LuceneVersion.LUCENE_48); // Define the per-field analyzers var perFieldAnalyzers = new Dictionary<string, Analyzer> { { "name", new KeywordAnalyzer() } // Use KeywordAnalyzer for "name" }; // Combine default and per-field analyzers _perFieldAnalyzerWrapper = new PerFieldAnalyzerWrapper(_defaultAnalyzer, perFieldAnalyzers); } protected override TokenStreamComponents CreateComponents(string fieldName, System.IO.TextReader reader) { // Delegate to the PerFieldAnalyzerWrapper return _perFieldAnalyzerWrapper.GetWrappedAnalyzer(fieldName).CreateComponents(fieldName, reader); } protected override TextReader InitReader(string fieldName, TextReader reader) { return _perFieldAnalyzerWrapper.InitReader(fieldName, reader); } } ``` -- This is an automated message from the Apache Git Service.
