Hi,
Thanks for your reply.
I can use the getTermFreqVector() on Index Reader and get it. But I am
wondering whats the API which has to be used to find the similarity between

I want to set documents in my IndexReader as deleted, but I will
never commit these deletions. Sort of a filter on a reader rather

Can I do that out of the box?
Perhaps I can pass down a IndexDeletionPolicy to my IndexWriter that
ignores deletions fr

Action book covers dates as well, although it might be a bit dated.
Lucene also comes with sort
Greatly appreciated.
It works perfect.

I am using the most basic lucene functionality but using against a
database. For example, I may have a message forum and will index that
message text and message subject from the database. But I haven't
figured out a way to index the date. ideally, when I search I should
