Hi,
I want to update a document in the lucene index. As mentioned in the
documentation, I tried to delete the document using IndexReader.delete
method. But even after I delete the document, I am able to see the
document when I perform a search. I thought this could be because, I am
caching the IndexSearcher instance and refreshing it only when required.
So I tried to refresh the IndexSearcher instance immediately after
deletion. But even this did not solve the problem. Here is the code:
public synchronized void deleteDocument(String id) {
String indexLoc = luceneConfig.getIndexDir();
Directory fsDir = getIndexDirectory(indexLoc, false);
IndexReader reader = getIndexReader(fsDir);
try {
Term t = new Term(IndexSearchConstants.DOCUMENT_ID, id);
reader.delete(t);
//After deleting the document refresh the IndexSearcher instance
manager.refreshIndexSearcher();
} catch (IOException e) {
logger.error("IOException occurred in deleteDocument()", e);
} finally {
try {
reader.close();
} catch(IOException e) {}
}
}
The document seems to be deleted only when I restart the server. Am I
missing something while deleting the document? When does the document
actually get deleted from the index?
Thanks,
Harini
