Hello, I would like to add RAMDirectory to another machines' FSDirectory Can I treat a RAMDirectory as Serializable ? I found RAMDirectory and Serializable discussion a long time ago in the dev list. But I cound find the answer. Thanks. Youngho

AW: cancel search

Exceptions didn't work as you need to implement the HitCollector class. Its method "collect" doesn't throw any exceptions and I don't want to rewrite anything of Lucene, so I'm using "searcher.close()" instead: public class TimedHitCollector extends HitCollector { private Searcher searcher;

You could always create a subclass of RuntimeException and throw and catch this instead. "Kunemann Frank" <[EMAIL PROTECTED]> wrote on 09/09/2005 10:01:56: > Exceptions didn't work as you need to implement the HitCollector > class. Its method "collect" doesn't throw any exceptions and I don'

howto pronounce Plucene?

How do you pronounce Plucene, a Perl port of Lucene? I think we can pronounce it as [p-lucene] or [plucene]. -- Cheolgoo - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RAMDirectory and Hibernate

Hi, I want to map RAMDirectory to a database via Hibernate. Any ideas on how to do this properly? I thought of using JDBCDirectory for this, but I need to support more databases than MySQL and PostgreSQL. Many thanks, Peter - To

Re: IndexReader delete doc! delete terms?

Nope. The IndexReader simply sets a bit in a separate bitvector that marks the doc as deleted. All info associated with the document are removed after an IndexWriter merges the segment containing that doc with another (optimize will merge all segments and hence remove remnants of all deleted doc

Re: howto pronounce Plucene?

Hello Cheolgoo, I always pronounce the "plu" part as "plu" in the word "plus", and "cene" as the word "seen". Something like pluseen. But you could also ask on the Plucene mailing list, maybe they pronounce it differently. Otis --- Cheolgoo Kang <[EMAIL PROTECTED]> wrote: > How do you pronou

BooleanQuery or QueryFilter?

I know this question has been asked before, but I'm not certain of what would work best for my scenario. So here goes... I have an index with documents that carry a broad number of keyword fields, usually containing numeric Ids (no sorting, so no leading zeros). From a set of search results, I

Speed of complex boolean searches on large indexes

Hi, I am testing the speed of searching Lucene indexes. The index is of the larger size! It has about 500,000 documents, about 60 fields with 1 field (Field1) containing the body of the document. Total index size is currently about 20Gb Testing the search i get this behaviour (Field2:1) AND (F

Re: Speed of complex boolean searches on large indexes

Well, by changing your query, you are changing your criteria, so I assume you also got different (less) results. That's one reason why your query got faster. If index size is the issue, and that Field1 consumes most of it, and you are not using it in search (I don't see it in your sample query), e

Re: BooleanQuery or QueryFilter?

Sounds like a job for a Filter and CachingWrapperFilter (see http://www.lucenebook.com/search?query=caching+filter ). Chris Hostetter wrote a nice email about how he did this for C|Net maybe 1-2 weeks ago. Should be in the mailing list archives. Otis --- Jeff Rodenburg <[EMAIL PROTECTED]> wrote

Re: howto pronounce Plucene?

I would say 'plu' as in Pluto because Lucene sounds like LouSeen, unless I've been saying it wrong and Lucene should sound like LusSeen, it which case it would be 'plu' like 'plus'. On 9/9/05, Otis Gospodnetic <[EMAIL PROTECTED]> wrote: > Hello Cheolgoo, > > I always pronounce the "plu" part as

Ah, sorry, I was thinking of "plus" in the wrong language. Weird. Yes, that's "plu" as in "Pluto". Otis --- Thomas Lepkowski <[EMAIL PROTECTED]> wrote: > I would say 'plu' as in Pluto because Lucene sounds like LouSeen, > unless I've been saying it wrong and Lucene should sound like > LusSeen,

Hardware recommendation

Hi, I'm putting together a cheap indexing server for an "explorative" lucene project and had a few questions about which route to go. I am going with a Socket 939 platform - does it make sense to get the dual core Athlon 64 X2, or is it better to stick with a faster clocked "plain" Athlon 64? Al

Re: Reducing number of poor results from large BooleanQueries

Isn't the trouble with introducing a scoring threshold based on raw scores that the Similarity scoring mechanism is considering each document in isolation? At this stage we don't know if the query is generally a good one or not (ie spelt correctly, and not a Googlewhack combination of rarely co

Re: RAMDirectory add index with other machine FSDirectory

Save it to disk using FSDirectory, zip the index directory, and copy it to the remote host over the socket. There is no built-in Lucene-way of doing this. You can also simply scp the index directory or use whatever other file transfer protocol suits you. Otis --- Youngho Cho <[EMAIL PROTECTED]>

Re: RAMDirectory add index with other machine FSDirectory

Cause the RAMDirectory is not serializable, it's hard to send a index to a remote computer. I think it's kind of tricky, but it would work. 1. Create a fresh new IndexWriter(let's name it toTransfer) with temporary FSDirectory, /usr/tmp/some/directory for example. 2. Invoke the toTransfer.addIndex
