Summary: Lucene54DocValuesProducer#getSortedSetTable lookupTerm
does not honor lookupTerm
Key: LUCENE-7851
URL: https://issues.apache.org/jira/browse/LUCENE-7851
Project: Lucene - Core
Issue Type: Bug
Reporter: Vesa Pirila
I'm having a problem with the lookupTerm method of the anonymous
RandomAccessOrds class returned by
Lucene54DocValuesProducer#getSortedSetTable(). It does not seem to honor
setDocument. It returns the same ord every time regardless of my calling
setDocument with different arguments.
To reproduce:
I have two documents with a multi-valued string field "strfield". Both have a
single value "a". I have a custom class that extends FieldCacheSource. This is
obviously just a dummy, but it's the simplest way I know to reproduce the
problem.
public class MyValueSource extends FieldCacheSource {
public MyValueSource(String field) {
super(field);
}
@Override
public FunctionValues getValues(Map map, LeafReaderContext readerContext)
throws IOException {
SortedSetDocValues dvs = DocValues.getSortedSet(readerContext.reader(),
FieldNames.PARENTS_DATES);
dvs.setDocument(0);
long zeroOrd = dvs.lookupTerm(new BytesRef("a"));
dvs.setDocument(1);
long oneOrd = dvs.lookupTerm(new BytesRef("a"));
assert(zeroOrd != oneOrd); // FAILS. The same ord is always returned.
return new LongDocValues(this) {
@Override
public long longVal(int doc) {
return 0;
}
};
}
}
