Re: java on 64 bits

Thank you, Yonik, it seems this is the case. What can we do in this case? Would running the program with java -d32 be a solution? Thanks again, roxana One possibility: if lucene runs out of memory while adding or optimizing, it can leave unused files beind that increase the size of the index.

Re: java on 64 bits

You can also try to clean up index with Luke. Yonik Seeley wrote: One possibility: if lucene runs out of memory while adding or optimizing, it can leave unused files beind that increase the size of the index. A 64 bit JVM will require more memory than a 32 bit one due to the size of all referenc

Re: Lucene search is very slow

You can create the new instance of IndexSearcher right after you finish updating the index. And when the new IndexSearcher is ready, switch to the new one and close the old one. I use Hits object to do pagination too. No problem there. Chris -- Full-Text Search on

Re: How To Implement Google Adwords-Like Text Ad?

With Google TextAds, I've noticed on my blog that the text ads take a little while to get updated to correspond to the new content, which seems to imply that they take note of the new blog content and decide which text ads to serve up. The question is, if this is true, how can it done quickly

Non scored results

Hello all. If I need non scored results can I use Searcher.search(Query,HitCollector) method and store bitset of found documents. will it give me some speed improvement? thanks. -- regards, Volodymyr Bychkoviak - To unsubs

Re: Non scored results

It can... By the time the hitcollector is called, the documents are already scored, so you don't save any time there. But since they haven't been sorted yet, you do save the time it would take to put all the hits through the priority queue to find the top "n". -Yonik On 10/21/05, Volodymyr Bychk

Re: java on 64 bits

1) make sure the failure was due to an OutOfMemory exception and not something else. 2) if you have enough memory, increase the max JVM heap size (-Xmx) 3) if you don't need more than 1.5G or so of heap, use the 32 bit JVM instead (depending on architecture, it can acutally be a little faster becau

RE: java on 64 bits

I have seen quite a few posts on using the 1.9 dev version for production uses. How stable is it? Is it really ready for production? I would like to use it.. but I never ever put beta packages in procution.. but then again.. I'm always dealing with Microsoft :) Tom -Original Message- Fro

Re: java on 64 bits

Hi, Also, I think you may try to increase the indexInterval, it is set to 128, but getting it larger, the .tii files will be smaller. Since .tii files are loaded into memory as a whole, so, your memory usage might be smaller. However, this change might affect your search speed. So, be careful abou

Re: java on 64 bits

Thanks everyone for the answers! I'm experimenting with your suggestions, I will let you know if something interesting pops up. roxana 1) make sure the failure was due to an OutOfMemory exception and not something else. 2) if you have enough memory, increase the max JVM heap size (-Xmx) 3) if

Re: How To Implement Google Adwords-Like Text Ad?

But can the Bayesian classifier narrow down the ads precise enough? When I look at Google Text Ads, they are really precise. For examples, if I search "PHP" in google or it's a webpage about PHP, it doesn't show ads just because they are computer science related, it just shows the ones that is
