Do Lucene Deletes delete the physical file? If yes, is there a way not to?

[David Lee <da...@gmail.com>]

Is it possible to delete a document from the index, but not the physical
file. And also I'm wondering what the functions are that will alter the
physical files being indexed.

On a side note: what is the best way to look up information like this so I
don't have to bug the java-user mailing list for simple questions like this?
I tried googling, but didn't seem to get the information I wanted. Thanks!

Documents are not deleted until you optimize the index. Perhaps they  
are deleted at merge time too? Until that point documents deleted are  
marked in a seperate file.

Is there a specific problem behind your question? There might be  
alternative solutions.

Generally I'd suggest getting the source code and follow it to see  
what happends. If you need documentation then there are some links here:
