Re: Lucene 1.9.1 - How to determine from which machine the hit comes?

Hi, Yes, the 2nd case, we have a MultiSearcher taking an array of Searchable (each doing the lookup to different server machines) on the client side and RemoteSearchable taking an instance of MultiSearcher on the server side. How to find out which searcher a hit comes from with a MultiSearcher?

Re: Data structure of a Lucene Index

I have already gone through the fileformat. What I was looking for, is the underlying theory behind the chosen fileformats. I am sure those fileformats were decided based on some theoritical axioms. --prasen [EMAIL PROTECTED] wrote: On Mar 28, 2006, at 11:57 PM, Prasenjit Mukherjee wrote:

Jelda, I have just added a patch for DisjunctionSumScorer.java here: https://issues.apache.org/jira/browse/LUCENE-413 issue. Could you try that patch and report the results at the jira issue? In case you need help using the patch could you move the discussion to the java-dev list? Regards, Paul

Re: Boosting a token in the query

Unfortunately I'm not sure what boosting capabilities were available in 1.2, but that syntax is correct for the 1.4+ at least. And I'm sure the Explanation feature is not available in 1.2, but with more recent versions of Lucene you'd be able to see the effect of the boosts on the score.

Should I reindex with remove then add or can I add then remove?

What is the largest index(s) size lucene can support

I know Lucene can have multiple indexes and have a parallel search across indexes. The question I have is what is the largest number of documents Lucene can support with multiple distributed indexes. Or if to be more specific, can Lucene support BILLIONS of documents (across multiple indexes), and

Re: Hi Experts

Hi, Lucene is a component that indexes data and allows you to search that indexed data, you need to be able to program in Java(various ports for other languages are available) or find a crawler you can adapt to download the required data of the internet (still requires basic knowledge of Ja

Boosting a token in the query

Is there a way to boost a token while querying? Example, in the following query +(DESC:sheets DESC:sheet), can the token 'sheets' be boosted and given higher precedence over 'sheet' so the results matching 'sheets ' appear before those for 'sheet'? I am using lucene 1.2. I tried using the boost fac

Thank you~ The sorting doesn't seem to take that long (not as long as I expected), but unfortunately didn't get to measure it this time... Maybe next time I'l try measuring.. Now I've got another problem.. My final goal is to keep the index sorted reverse-chronologically, so that, when searching,

Well you'll have to index the internet. Then when you've done that then you can try going against google. Oh, and you'll have to update that index every now and then to keep your index of the internet updated. Good luck. --- I²R Disclaimer ---

RE: Hi Experts

Thanks Aditya, Lucene is used only to search in the local machine right? How can lucene search on the internet? Do we have any tools which can index on the internet self and displays the results. I know this is very silly. -Original Message- From: Aditya Liviandi [mailto:[EMAIL PROTECTED
