suchoss opened a new issue, #850:
URL: https://github.com/apache/lucenenet/issues/850
Having following query analyzer:
```csharp
internal class DefaultQA : Lucene.Net.Analysis.Analyzer
{
private LuceneVersion _version = Lucene.Net.Util.LuceneVersion.LUCENE_48;
protected override TokenStreamComponents CreateComponents(string
fieldName, TextReader reader)
{
Tokenizer tokenizer = new
Lucene.Net.Analysis.Standard.StandardTokenizer(_version, reader);
TokenStream result = new StandardFilter(_version, tokenizer);
result = new LowerCaseFilter(_version, result);
result = new ASCIIFoldingFilter(result);
return new TokenStreamComponents(tokenizer, result);
}
}
```
When I try to parse a query containing `&` sign, it will generate `AND`
query instead, even if `&` is escaped like this `\&`:
```csharp
var qa = new DefaultQA();
var queryParser = new QueryParser(Lucene.Net.Util.LuceneVersion.LUCENE_48,
"fieldName", qa)
{
DefaultOperator = Lucene.Net.QueryParsers.Classic.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);
```
Result of previous gives me following:
```
searchQuery = +fieldName:more +fieldName:more
searchQuery2 = fieldName:more fieldName:more
searchQuery3 = fieldName:"more more"
```
But I am expecting something like this:
```
searchQuery = +fieldName:more\&more
searchQuery2 = fieldName:more\&more
searchQuery3 = fieldName:"more\&more"
```
It seems to me that escaped characters are treated the same way as unescaped
ones.
