使用lucene更新文档字段

Question

i'm trying to update an indexed documents in lucene by searching for the document, and then extracting the indexed document fields, and then deleting the document and creating a new one. is there anther effective way for such an update?

Answer 1

There isn't. The best you can get is IndexWriter.updateDocument(Term term, Iterable<? extends IndexableField> document) but even this deletes and adds the same document again.
