Description
When building a boolean query of two spanqueryies, if one of the spanqueries does not have a hit, an ArrayIndexOutOfBoundsException is thrown.
This does not happen when building a boolean query of two TermQuery(ies), nor does it happen if all of the terms have a hit.
@Test
public void testBooleanSpanQuery() {
boolean failed = false;
int hits = 0;
try{
CharArraySet stops = CharArraySet.EMPTY_SET;
Analyzer indexerAnalyzer = new StandardAnalyzer(LuceneProjectVersion.LUCENE_VERSION, stops);
Directory directory = new RAMDirectory();
IndexWriterConfig config = new IndexWriterConfig(LuceneProjectVersion.LUCENE_VERSION, indexerAnalyzer);
IndexWriter writer = new IndexWriter(directory, config);
String FIELD = "content";
Document d = new Document();
d.add(new TextField(FIELD, "clockwork orange", Field.Store.YES));
writer.addDocument(d);
writer.close();
IndexReader indexReader = DirectoryReader.open(directory);
IndexSearcher searcher = new IndexSearcher(indexReader);
BooleanQuery query = new BooleanQuery();
SpanQuery sq1 = new SpanTermQuery(new Term(FIELD, "clockwork"));
SpanQuery sq2 = new SpanTermQuery(new Term(FIELD, "clckwork"));
query.add(sq1, BooleanClause.Occur.SHOULD);
query.add(sq2, BooleanClause.Occur.SHOULD);
TopScoreDocCollector collector = TopScoreDocCollector.create(1000, true);
searcher.search(query, collector);
hits = collector.topDocs().scoreDocs.length;
for (ScoreDoc scoreDoc : collector.topDocs().scoreDocs)
} catch (java.lang.ArrayIndexOutOfBoundsException e)
{ failed = true; }catch (IOException e)
{ e.printStackTrace(); } assertEquals("Bug in boolean query composed of span queries", failed, false);
assertEquals("Bug in boolean query composed of span queries", hits, 1);
