Description

Hello,
I can not find out, why (and what) it is happening all the time. I got an
exception:
java.lang.IllegalStateException: docs out of order
at
org.apache.lucene.index.SegmentMerger.appendPostings(SegmentMerger.java:219)
at
org.apache.lucene.index.SegmentMerger.mergeTermInfo(SegmentMerger.java:191)
at
org.apache.lucene.index.SegmentMerger.mergeTermInfos(SegmentMerger.java:172)
at org.apache.lucene.index.SegmentMerger.mergeTerms(SegmentMerger.java:135)
at org.apache.lucene.index.SegmentMerger.merge(SegmentMerger.java:88)
at org.apache.lucene.index.IndexWriter.mergeSegments(IndexWriter.java:341)
at org.apache.lucene.index.IndexWriter.optimize(IndexWriter.java:250)
at Optimize.main(Optimize.java:29)

It happens either in 1.2 and 1.3rc1 (anyway what happened to it? I can not find
it neither in download nor in version list in this form). Everything seems OK. I
can search through index, but I can not optimize it. Even worse after this
exception every time I add new documents and close IndexWriter new segments is
created! I think it has all documents added before, because of its size.

My index is quite big: 500.000 docs, about 5gb of index directory.

It is repeatable. I drop index, reindex everything. Afterwards I add a few
docs, try to optimize and receive above exception.

My documents' structure is:
static Document indexIt(String id_strony, Reader reader, String data_wydania,
String id_wydania, String id_gazety, String data_wstawienia)
{
Document doc = new Document();

doc.add(Field.Keyword("id", id_strony ));
doc.add(Field.Keyword("data_wydania", data_wydania));
doc.add(Field.Keyword("id_wydania", id_wydania));
doc.add(Field.Text("id_gazety", id_gazety));
doc.add(Field.Keyword("data_wstawienia", data_wstawienia));
doc.add(Field.Text("tresc", reader));

return doc;
}

Sincerely,
legez
