-----------------------------
Summary: SimpleQueryParser stack overflow for large nested queries.
Key: LUCENE-10651
URL: https://issues.apache.org/jira/browse/LUCENE-10651
Project: Lucene - Core
Issue Type: Bug
Affects Versions: 9.2, 8.10, 9.1, 9.3
Reporter: Marc
The OpenSearch project received an issue [1] where stack overflow can occur for
large nested boolean queries during rewrite. In trying to reproduce this error
I've also encountered SO during parsing where queries expand beyond the default
1024 clause limit. This unit test will fail with SO:
{code:java}
public void testSimpleQueryParserWithTooManyClauses() {
StringBuilder queryString = new StringBuilder("foo");
for (int i = 0; i < 1024; i++) {
queryString.append(" | bar").append(i).append(" + baz");
}
expectThrows(IndexSearcher.TooManyClauses.class, () ->
parse(queryString.toString()));
}
{code}
I would expect this case to also fail with TooManyClauses, is my understanding
correct? If so, I've attempted a fix [2] that during parsing increments a
counter whenever a clause is added.
