Plugins: Analyzer Generators

To add a custom analyzer, one must implement the AbstractAnalyzerGenerator class and provide logic when your custom analyzer should be used.

public abstract class AbstractAnalyzerGenerator
{
public abstract Analyzer GenerateAnalyzerForIndexing(string indexName, Document document, Analyzer previousAnalyzer);

public abstract Analyzer GenerateAnalyzerForQuerying(string indexName, string query, Analyzer previousAnalyzer);
}

where:

• GenerateAnalyzerForIndexing returns an analyzer that will be used while performing indexing operation.
• GenerateAnalyzerForQuerying returns an analyzer that will be used while performing querying.

Example - Using different analyzer for specific index

public class CustomAnalyzerGenerator : AbstractAnalyzerGenerator
{
private const string SpecificIndexName = "Specific/Index";

public override Analyzer GenerateAnalyzerForIndexing(string indexName, Document document, Analyzer previousAnalyzer)
{
	if (indexName == SpecificIndexName)
	{
		return new WhitespaceAnalyzer();
	}

	return previousAnalyzer;
}

public override Analyzer GenerateAnalyzerForQuerying(string indexName, string query, Analyzer previousAnalyzer)
{
	if (indexName == SpecificIndexName)
	{
		return new WhitespaceAnalyzer();
	}

	return previousAnalyzer;
}
}
