[jira] [Updated] (LUCENE-9367) Using a queryText which results in
zero tokens causes a query to be built as null
[ https://issues.apache.org/jira/browse/LUCENE-9367?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Tim Brier updated LUCENE-9367:
------------------------------
Description:
If a queryText produces zero tokens after being processed by an Analyzer, when you try to build a Query with it the result is null.
The following code reproduces this bug:
{code:java}
public class LuceneBug {
public Query buildQuery() throws IOException {
Analyzer analyzer = CustomAnalyzer.builder()
.withTokenizer(StandardTokenizerFactory.class)
.addTokenFilter(StopFilterFactory.class)
.build();
QueryBuilder queryBuilder = new QueryBuilder(analyzer);
String onlyStopWords = "the and it";
return queryBuilder.createPhraseQuery("AnyField", onlyStopWords);
}
}
{code}
