Tamas Sandor commented on LUCENE-2863:
--------------------------------------
Yeah, but how can I add the indexed fields back (tries of _LAT_, _LNG_ and the
_PATTERN_ field)?
{{document.getFields()}} would give my old fields back in the form on
{{List<Fieldable>}} but the comment says:
{quote}
Note that fields which are not stored are not available in documents retrieved
from the index, e.g. Searcher.doc(int) or IndexReader.document(int).
{quote}
So this won't work either:
{code:java}
doc = searcher.doc(hits.scoreDocs[0].doc);
Document ndoc = new Document();
for (Fieldable field : doc.getFields()) {
ndoc.add(field);
}
ndoc.add(new Field("FINAL", "FINAL", Store.YES, Index.NOT_ANALYZED_NO_NORMS));
writer.updateDocument(t, ndoc);
{code}
> Updating a documenting looses its fields that only indexed, also NumericField
> tries are completely lost

> URL: https://issues.apache.org/jira/browse/LUCENE-2863
> Project: Lucene - Java
> Issue Type: Bug
> Components: Store
> Affects Versions: 3.0.2, 3.0.3
> Environment: WindowsXP, Java1.6.20 using a RamDirectory
> Reporter: Tamas Sandor
> Priority: Blocker
>
> I have a code snippet (see below) which creates a new document with standard
> (stored, indexed), *not-stored, indexed-only* and some *NumericFields*. Then
> it updates the document via adding a new string field. The result is that all
> the fields that are not stored but indexed-only and especially NumericFields
> the trie tokens are completly lost from index after update or delete/add.
> {code:java}
> Directory ramDir = new RamDirectory();
> IndexWriter writer = new IndexWriter(ramDir, new WhitespaceAnalyzer(),
> MaxFieldLength.UNLIMITED);
> Document doc = new Document();
> doc.add(new Field("ID", "HO1234", Store.YES, Index.NOT_ANALYZED_NO_NORMS));
> doc.add(new Field("PATTERN", "HELLO", Store.NO, Index.NOT_ANALYZED_NO_NORMS));
> doc.add(new NumericField("LAT", Store.YES,
> true).setDoubleValue(51.488266037777066d));
> doc.add(new NumericField("LNG", Store.YES,
> true).setDoubleValue(-0.08913399651646614d));
> writer.addDocument(doc);
> doc = new Document();
> doc.add(new Field("ID", "HO2222", Store.YES, Index.NOT_ANALYZED_NO_NORMS));

> IndexSearcher seacher = new IndexSearcher(writer.getReader());
> TopDocs hits = seacher.search(q, 1);
> if (hits.scoreDocs.length > 0) {
> Document ndoc = seacher.doc(hits.scoreDocs[0].doc);
> ndoc.add(new Field("FINAL", "FINAL", Store.YES,

> LOG.info("_____hits HELLO:" + hits.totalHits); // should be 1 but it's 0
> writer.close();

> And I have a boundingbox query based on *NumericRangeQuery*. After the
> document update it doesn't return any hit.
