@suchoss Thanks for filing this report, but I have reproduced this in Java
Lucene 4.8 and it produces the same result, therefore this is not a bug with
our project. With modifications to the code below, I also reproduced the same
result in Lucene 10.0.0. If you feel this is a bug, please file an issue with
the upstream project. Thanks!
```java
package org.example;
import org.apache.lucene.analysis.Analyzer;
import org.apache.lucene.analysis.TokenStream;
import org.apache.lucene.analysis.Tokenizer;
import org.apache.lucene.analysis.core.LowerCaseFilter;
import org.apache.lucene.analysis.miscellaneous.ASCIIFoldingFilter;
import org.apache.lucene.analysis.standard.StandardFilter;
import org.apache.lucene.analysis.standard.StandardTokenizer;
import org.apache.lucene.util.Version;
import java.io.Reader;
public class DefaultQA extends Analyzer
{
private Version _version = Version.LUCENE_48;
@Override
protected TokenStreamComponents createComponents(String s, Reader
reader) {
Tokenizer tokenizer = new StandardTokenizer(_version, reader);
TokenStream result = new StandardFilter(_version, tokenizer);
result = new LowerCaseFilter(_version, result);
result = new ASCIIFoldingFilter(result);
return new TokenStreamComponents(tokenizer, result);
}
}
```
```java
package org.example;
import org.apache.lucene.queryparser.classic.ParseException;
import org.apache.lucene.queryparser.classic.QueryParser;
import org.apache.lucene.util.Version;
public class Main {
public static void main(String[] args) throws ParseException {
var qa = new DefaultQA();
var queryParser = new QueryParser(Version.LUCENE_48, "fieldName",
qa);
queryParser.setDefaultOperator(QueryParser.Operator.AND);
var query = QueryParser.escape("more&more"); //this is the query I
am trying to "parse"
var searchQuery = queryParser.parse(query);
var searchQuery2 = queryParser.createBooleanQuery("fieldName",
query);
var searchQuery3 = queryParser.createPhraseQuery("fieldName", query);
System.out.println(searchQuery);
System.out.println(searchQuery2);
System.out.println(searchQuery3);
}
}
```
output:
```
+fieldName:more +fieldName:more
fieldName:more fieldName:more
fieldName:"more more"
```
