I am a novice in lucene. I write some code to do batch indexing using
RAMDirectory according to the code provided in lucene in action, which is
something like FSDirectory fsDir = FSDirectory.getDirectory("/tmp/index",
true);
RAMDirectory ramDir = new RAMDirectory();
IndexWriter fsWriter = IndexWriter(fsDir,
new SimpleAnalyzer(), true);
IndexWriter ramWriter = new IndexWriter(ramDir,
new SimpleAnalyzer(), true);
while (there are documents to index) {
... create Document ...
ramWriter.addDocument(doc);
if (condition for flushing memory to disk has been met) {
fsWriter.addIndexes(Directory[] {ramDir});
ramWriter.close();
ramWriter = new IndexWriter(ramDir, new SimpleAnalyzer(),
true);
}
}
But it cannot compile correctly on fsWriter.addIndexes(Directory[]
{ramDir}); It seems some problem with ramDir. Is there something changed at
lucene 2.0? How can I implement batch indexing correctly? Any simple code.
Thanks!
Eric
