Hi, I have the following scenario: I have an index of very large size (although I'm testing with around 200,000 documents, but should scale to many millions) and I want to perform a search on a certain field. According to that search, I would like to manipulate a different field for all the matching documents. The only approach I could come up with so far would be to load the matching documents ids into a Collector, iterate over them, load the Document objects with IndexReader.document(docid), and manipulate them one by one. Finally, I would delete all the documents matching the initial query with IndexWriter.deleteDocuments(Query query) and write the edited ones with IndexWriter.addDocuments(Iterable<? extends Iterable<? extends IndexableField>> docs)
However, the iteration seems to be very time-consuming as it can concern large portions of the indexed documents and I wonder if there is a smarter way to perform the document manipulation. This is limited to one field only (not the one on which the query is typically performed!), shouldn't that help? Thanks!
