Error merging indices with Lucene 1.3 RC1
Hi all!
I am working with Lucene 1.3 RC1 and found what I think is a problem.
Basically, I am indexing into a RAMDirectory and then using addIndexes to
merge the RAMDirectory into a file system index. Adding in a small
number of documents doesn't seem to work.
My test code is like this:
Directory memDir = new RAMDirectory();
File tempDir = new File(System.getProperty("user.dir"), "test2");
Directory fsDir = FSDirectory.getDirectory(tempDir, true);
IndexWriter fsWriter =
new IndexWriter(fsDir, new StandardAnalyzer(), true);
IndexWriter memWriter =
new IndexWriter(memDir, new StandardAnalyzer(), true);
Document toAdd1 = createADocument(); // creates a random document
Document toAdd2 = createADocument();
memWriter.addDocument(toAdd1);
memWriter.addDocument(toAdd2);
String[] files = memDir.list();
for(int i=0;i<1;i++){
System.out.println(files[i]); // Only lists "segments" file,
no data files
}
fsWriter.addIndexes(new Directory[] { memDir });
fsWriter.close();
IndexReader reader =
IndexReader.open(FSDirectory.getDirectory(tempDir, false));
Document toCompare = reader.document(1); // Results in
ArrayIndexOutofBoundsException
reader.close();
tempDir.delete();
I should be able to get the document at index 1, but it fails. If I add in
12 documents by doing this:
memWriter.addDocument(toAdd1);
memWriter.addDocument(toAdd2);
for(int i=0;i<10;i++){
memWriter.addDocument(createADocument());
}
I only see 10 documents returned by IndexReader.termDocs(Term) on the
FSDirectory after I merge the RAMDirectory in. Any insights on why this may
be? Am I doing something wrong in this code?
Thanks in advance for any insights.
Joe W.
