java.lang.Object

org.apache.lucene.analysis.Analyzer

org.apache.lucene.analysis.util.StopwordAnalyzerBase

org.opencms.search.galleries.CmsGallerySearchAnalyzer

所有已实现的接口:

java.io.Closeable, java.lang.AutoCloseable

public class CmsGallerySearchAnalyzer
extends org.apache.lucene.analysis.util.StopwordAnalyzerBase

Special analyzer for multiple languages, used in the OpenCms gallery search index.

The gallery search is done in one single index that may contain multiple languages.

According to the Lucene JavaDocs (3.0 version), the Lucene StandardAnalyzer is already using "a good tokenizer for most European-language documents". The only caveat is that a list of English only stop words is used.

This extended analyzer used a compound list of stop words compiled from the following languages:

• English
• German
• Spanish
• Italian
• French
• Portugese
• Danish
• Dutch
• Catalan
• Czech

从以下版本开始:

8.0.0
