I would like to perform a batch update on an index. In order to omit duplicate
entries I am making use of IndexWriter#updateDocument(Term, Document)
open an IndexWriter;
foreach( element in elementsToBeUpdatedWhichHaveDuplicates )
{
doc = element.toDoc();
indexWriter.updateDocument( uniqueTermForElement, doc );
}
Unfortunately this does not seem to work, whereas
open an IndexWriter;
foreach( element in elementsToBeUpdatedWhichHaveDuplicates )
{
doc = element.toDoc();
indexWriter.updateDocument( uniqueTermForElement, doc );
indexWriter.commit(); // expensive?
}
does. How can I batchupdate without commiting?
