-----------------------------------------
Hi !
Sorry, but it was my first bug request.
You resolved the bug because you can not reproduce.
Here is the a simple example code, which demonstrate the problem:
public class WildcardTest
{
public static void main(String[] args) throws Exception
{
Analyzer analyzer = new GermanAnalyzer();
RAMDirectory indexStore = getIndexStore("fulltext", new
String[]{"Forschungsgebiet", "business"}, analyzer);
IndexSearcher searcher = new IndexSearcher(indexStore);
QueryParser parser = new QueryParser( "fulltext", analyzer );
Query query1 = parser.parse("fulltext:Forschungsgebie*");
Query query2 = parser.parse("fulltext:Forschungsgebiet*");
Hits result = searcher.search(query1);
System.out.println( query1.toString() );
System.out.println( "Query '" + query1.toString() + "' found: " +
result.length() + " documents !");
result = searcher.search(query2);
System.out.println( query2.toString() );
System.out.println( "Query '" + query2.toString() + "' found: " +
result.length() + " documents !");
searcher.close();
indexStore.close();
}
private static RAMDirectory getIndexStore(String field, String[] contents,
Analyzer p_Analyzer)
throws IOException
{
RAMDirectory indexStore = new RAMDirectory();
IndexWriter writer = new IndexWriter(indexStore, p_Analyzer, true);
for (int i = 0; i < contents.length; ++i)
{
Document doc = new Document();
doc.add(new Field(field, contents[i], Field.Store.YES,
Field.Index.TOKENIZED));
writer.addDocument(doc);
}
writer.optimize();
writer.close();
return indexStore;
}
}
Output:
Query 'fulltext:forschungsgebie*' found: 1 documents !
Query 'fulltext:forschungsgebiet*' found: 0 documents !

> WildcardQuery do not find documents
> -----------------------------------
>
> Key: LUCENE-838
> URL: https://issues.apache.org/jira/browse/LUCENE-838
> Project: Lucene - Java
> Issue Type: Bug
> Components: Search
> Affects Versions: 1.9, 2.0.0, 2.1
> Environment: Windows XP; JDK 1.5
> Reporter: Michael Schlegel
>
> Example:
> I index a document by using GermanAnalyzer.
> This document contains following word "Forschungsgebiet".
> This word will be analyzed and transformed to "Forschungsgebie".
> If i use query "Forschungsgebiet" to search the document, i will find the
> document.
> If i use query "Forschungsgebie*" or "Forschung*" i will find the document
> too.
> But if i use query "Forschungsgebiet*" or "?orschungsgebiet" i never will
> find this document.
> It looks so that the query will not be analyzed by the given Analyzer and
> thatswhy i will not find the document (Forschungsgebiet !=
> Forschungsgebie).
> The same can happen if a other analyzer is used.
