--------------------------------------
Summary: Flattening of nested disjunctions does not take into
account number of clause limitation of builder
Key: LUCENE-8810
URL: https://issues.apache.org/jira/browse/LUCENE-8810
Project: Lucene - Core
Issue Type: Bug
Components: core/search
Affects Versions: 8.0
Reporter: Mickaël Sauvée
Fix For: 8.1.1
In org.apache.lucene.search.BooleanQuery, at the end of the function
rewrite(IndexReader reader), the query is rewritten to flatten nested
disjunctions.
This does not take into account the limitation on the number of clauses in a
builder (1024).
In some circumstances, this limite can be reached, hence an exception is
thrown.
Here is a unit test that highlight this.
{code:java}
public void testFlattenInnerDisjunctionsWithMoreThan1024Terms() throws
IOException {
IndexSearcher searcher = newSearcher(new MultiReader());
BooleanQuery.Builder builder1024 = new BooleanQuery.Builder();
for(int i = 0; i < 1024; i++) {
builder1024.add(new TermQuery(new Term("foo", "bar-" + i)), Occur.SHOULD);
}
Query inner = builder1024.build();
Query query = new BooleanQuery.Builder()
.add(inner, Occur.SHOULD)
.add(new TermQuery(new Term("foo", "baz")), Occur.SHOULD)
.build();
searcher.rewrite(query);
}
{code}
