marko-bekhta opened a new issue, #13234:
URL: https://github.com/apache/lucene/issues/13234
### Description
Assume there's a query parser created, e.g.:
```java
Analyzer analyzer = new ClassicAnalyzer();
QueryParser queryParser = new QueryParser( "field", analyzer );
```
trying to parse simple ranges like:
```java
// simple range query with no escapes works fine:
Query query = queryParser.parse( "[ 1 TO 10 ]" );
```
works as expected and a `TermRangeQuery` is created with no exceptions.
But if the range in the string contains some escaped brackets -- it leads to
a parsing exception.
Let's assume one would want to extend the query parser to work with
date-time fields and would want to parse something like:
```java
// another range query but now it has some escaping between the range
brackets:
query = queryParser.parse( "[
2024\\-01\\-01T01\\:01\\:01\\+01\\:00\\[Europe\\/Warsaw\\] TO
2025\\-01\\-01T01\\:01\\:01\\+01\\:00\\[Europe\\/Warsaw\\] ]" );
```
where all special characters are escaped, leads to:
```java
Caused by: org.apache.lucene.queryparser.classic.ParseException: Encountered
" "]" "] "" at line 1, column 50.
Was expecting:
"TO" ...

org.apache.lucene.queryparser.classic.QueryParserBase.parse(QueryParserBase.java:137)
... 4 more
```
Note, the idea to do range queries for dates is to have something along the
lines:
```java
QueryParser queryParser = new QueryParser( "field", analyzer ) {
@Override
protected Query newRangeQuery(String field, String part1, String part2,
boolean startInclusive, boolean endInclusive) {
var p1 = parseValue(part1);
var p2 = parseValue(part2);
return createRangeQueryForDates( field, p1, p2, startInclusive,
endInclusive );
}
};
```
but because of the parsing error described above, execution never reaches
this point.
