2.4.x index cannot be opened with 2.9-dev
-----------------------------------------
Key: LUCENE-1739
URL: https://issues.apache.org/jira/browse/LUCENE-1739
Project: Lucene - Java
Issue Type: Bug
Components: Index
Reporter: Robert Muir
Sorry for the lack of proper testcase.
In 2.4.1, if you created an index with the (stupid) options below, then it will
not create a .prx file. 2.9 expects this file and will not open the index.
The reason i used these stupid options is because i changed the field from
indexed=yes to indexed=no, but forgot to remove the .setOmitTf()
{code}
public class Testcase {
public static void main(String args[]) throws Exception {
/* run this part with lucene 2.4.1 */
IndexWriter iw = new IndexWriter("test", new
WhitespaceAnalyzer(), IndexWriter.MaxFieldLength.LIMITED);
iw.setUseCompoundFile(false);
Document doc = new Document();
Field field1 = new Field("field1", "foo", Field.Store.YES,
Field.Index.NO);
field1.setOmitTf(true); // 2.9 will create a 0-byte .prx file,
but 2.4.x will NOT. This is the problem. 2.9 expects this file!
doc.add(field1);
iw.addDocument(doc);
iw.close();
/* run this with lucene 2.9 */
IndexReader ir =
IndexReader.open(FSDirectory.getDirectory("test"), true);
}
}
{code}
