> Hi,
> When I use the API as below :
> {code}
> List<CategoryPath> categories = Collections.<CategoryPath>singletonList(new
> CategoryPath(path.toArray(new String[path.size()])));
> FacetFields facetFields = new FacetFields(taxonomyWriter);
> facetFields.addFields(document, categories);
> taxonomyWriter.commit();
> {code}
> An exception occurs :
> {quote}
> java.util.NoSuchElementException
> at java.util.Collections$1.next(Collections.java:3302)
> at
> org.apache.lucene.facet.index.DrillDownStream.reset(DrillDownStream.java:78)
> at
> org.apache.lucene.index.DocInverterPerField.processFields(DocInverterPerField.java:97)
> at
> org.apache.lucene.index.DocFieldProcessor.processDocument(DocFieldProcessor.java:248)

> org.apache.lucene.index.DocumentsWriterPerThread.updateDocument(DocumentsWriterPerThread.java:253)

> at
> org.apache.lucene.index.IndexWriter.addDocument(IndexWriter.java:1171)
> {quote}
> Seems likes this is due to multiple calls to
> org.apache.lucene.facet.index.DrillDownStream#reset which invoques #next() on
> an 'used' iterator.
> Regards,
> Lucien
