Subject Re: IndexReader deleteDocument
Date Mon, 17 Mar 2008 08:12:43 GMT
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.

best.
