The trunk version of Lucene (eventually 2.4) now has deletion by
query, in IndexWriter.

Hello Erick,
Has anyone found a way for deleting a document with a query? I
understand it
can be deleted via terms, but I need to delete a document with two
terms,
that is the only way I can identify my document is by looking at
two terms
not one.

a document and optimizing (and other operations) can and will change
document IDs. So, yes, you have to do a search (either use a hits
object
or one of the HitCollectors) in order to delete by doc ID.
You can also delete by terms, see the API.
There are other options, but you haven't explianed what you're
trying to accomplish enough to offer any more suggestions.

No. I haven't but I will. even though I would like to make my own
implementation. So any idea of how to get the "doc num"?
Thanks for replying.

Hi,
I am trying to delete a document without using the hits object.
What is the unique field in the index that I can use to delete the
document?
I am trying to make a web interface where index can be modified,
smaller
subset of what Luke does but using JSPs and Servlet.
to use deleteDocument(int docNum)
I need docNum how can I get this? or does it have to come only vis
Hits?
Thanks,
Varun
