Hi,
In the search application I'm working on I would like to prevent the
user from getting always the same search results for a certain query,
but without affecting results quality too much.
In order to do so I'm processing the hits in smaller chunks and doing
some random shuffle inside the
Did you hit enter after that [input]... line? It's asking you to
confirm where you want the index written.
BTW you should send future questions about Lucene in Action 2 at the
book's forum, here:

Hi All,
I recently purchased Lucene in action 2nd edition. When i ran the suggested

"ant indexer" (located in Chapter 1: Running Indexer, page 21) it was able
to run for a while until it froze.

I wrote last week about the best way to paginate. I will reply back

How do you expose a pagination without a customized hit collector. The
multi searcher does not expose a method for hit collector and sort.
Maybe this is not an issue for people ...

Why not use a MultiSearcher an all single searchers? Or a Searcher on a
MultiReader consisting of all IndexReaders? With that you do not need to
merge the results.
By the way: instead of creating a TopDocCollector, you could also call

Probably not. That's certainly not tested or guaranteed. Pathological input

Allthough (I could be wrong) but I'm wondering if the lenthNorm is the
correct one I should be overriding. I'm interested in the number of times a
term occurs found in a document (more occurance the higher the score) which
I believe is coord. I may well be i am barking up the wrong tree.

If I choose to subclass the default similarity, do I need to apply the same

I am interested in doing the below:

Hello luceners,
query.toString() does a fair job at being reparsed by QueryParser but
is there a safe way to do so?

It's an easy mistake :)
Now that you're on 2.4.1 you can try switching back to using a String
path... that should work fine (since 2.4.1 fixes LUCENE-1453).

As I know, the demos are not compiled by default in the release (because
they show how you use Lucene and are so included as .java source files in
the binary distribution). You have to build the demos using ANT.
