update a specific document
Hi,
I want to update a specific document,
but i didn't found updateDocument(Query)
or updateDocument(Term[]), so to make
a update, i will need to have a term with an
unique id, so a retrieve a u)nique document,
There's any way of access the internal document
id?
For example, imagine that i have the id of document
to update, and i want to update(Term,Document) but passing
the internal id as Term.
cheers,
João

Hi,
thank you all for your answers. I already done the strategies you mencioned
by delete first and update or using the internal api updateDocument(term,
document).
If there was a updateDocument(internalid, theNewDocument) present
in the api, this clarified more the process.
Thanks again, for your fast answers,
i will do with a specific application id in one term.

Exactly, its cleaner but you wouldn't be able to delete on the basis of
Lucene Document ID.

Re: update a specific document

There's also IndexWriter#updateDocument(Term, Document) now, to use
that one you need to be able to uniquely identify a document using a
term (probably with an application-specific id field or something).
This method does also delete and readd the document, but it is a
somewhat cleaner api.

HI Galaio,
To update a document in lucene this way, you'd have to first delete the
document
using indexReader's delete document and then readd the document (thereby
changing the internal docId as well).
You may use:
http://lucene.apache.org/java/2_4_1/api/org/apache/lucene/index/IndexReader.html#deleteDocument(int)
