suchoss opened a new issue, #13962: URL: https://github.com/apache/lucene/issues/13962
### Description Having following code: ```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); } } ``` I am getting this result: ``` +fieldName:more +fieldName:more fieldName:more fieldName:more fieldName:"more more" ``` But what I expected was escaped query: ``` +fieldName:more\&more fieldName:more\&more fieldName:"more\&more" ``` It seems as bug to me that escaped query doesn't stay escaped. Original issue was found on Lucenenet (Lucene.NET) port ([https://github.com/apache/lucenenet/issues/850](https://github.com/apache/lucenenet/issues/850)) ### Version and environment details `Java Lucene 4.8`, but it was allegedly tested even in `Lucene 10.0.0` with the same results -- This is an automated message from the Apache Git Service.
