Re: Deleting a document found in a search
You mean d.get(Id); ?

understanding some basic concepts.
I am using two-part identifiers to uniquely identify a document in
the
index. So whenever I want to index a document, I first want to find
and
delete the old form.
To find it, I intend to use:
BooleanQuery findOurs = new BooleanQuery();
findOurs.add(new TermQuery(new Term(Id, id)), true, false);
findOurs.add(new TermQuery(new Term(Domain, domain)), true,
false);
System.out.println(Deleting document matching: \ +
findOurs.toString() + '');
Searcher searcher = new IndexSearcher(directory);
Hits hits = searcher.search(findOurs);
// Assert: hits.length() = 1
for (int i = 0 ; i hits.length() i 10; i++) {
Document d = hits.doc(i);
// Now what can I do to find document id?
int id = ??
searcher.delete(id);
}
But I can't discover how to convert a search result into a document
id. It
is recorded in the private HitDoc class, but since it is not publicly
accessible, there must be a reason why it would not work to add a
public
getter for it.
Is there an alternative way that I can do this? My first thought is
to
define a Field.Keyword(composite-key, domain + \u + id).
This
would allow me to use the delete(Term) interface to delete the key.

Re: Deleting a document found in a search
No, I mean HitDoc.id, the document number field stored in
the HitDoc class. This number is needed when calling
IndexReader.delete(int docnum) but it is not publicly
accessible.

That sounds like a good way to solve this. You could also use a HitCollector with a Query, but I think the composite key is a better approach.
