Re: Customized search with Lucene?

Lukas, Thanks for the link to the book, seems very interesting. Your original question made me think you are intending to maintain personalized score modifications - i.e. for each user you are going to custom the scores differently and I was curious to know how you are going to maintain custom sco

Same query different results?

I have two two similar query's that give me the same results when I run them in Luke, but when I run them in my app, one of the querys gives me the correct results and the other query gives me no results. I am using StandardAnalyzer in both Luke and my app. Query 1: This query works correctly in m

Re: Boost Sub-Query

What I'd do is get a copy of Luke, put the query in the appropriate box and click on the explain tab. Trying that several ways should answer your question as well as give you a better feel for how Lucene handles queries. Best Erick On 10/24/07, java_user_ <[EMAIL PROTECTED]> wrote: > > > Is it po

Re: Index Reader Writer - 2 JVMs

Lucene does provide locking so that two JVM's can access the same index. Check out the LockFactory to control how this is done. There are a couple advantages of using IndexAccessor: For one you could use a NoLockFactory and avoid Lucene's locking mechanism. Also, you would only need to run one

Doron, Sorry for the late reply. I got the inspiration for this question from book Programming Collective Intelligence by Toby Segaran (you can check herefor some O'Reilly's comments on the book). You can find a chapter Searching and

Re: Highlighter and href fields

Nothing in the Highlighter per seh that will help you there. I see two options off the top of my head: 1. break the text before feeding it to the highlighter and feed all but the URL parts, and then stitch back together -- much as you might do if highlighting an XML doc. Ugly though. 2. Use

Index Reader Writer - 2 JVMs

Hi All, I have a scenario where there are two processes (2 JVMs) accessing the same index. One of them is doing the indexing as documents arrive into the system and the second one servers search queries. Both the processes are running on the same machine. Is there a need to do some kind of lockin

Highlighter and href fields

Is there anyway I stop highlighting text if it is a href/url etc...? The problem occurs when the field content is a URL which contains the query e.g. my search is for .net and fields has value http://jkjsd.net. After applying highlighter, it becomes http://jkjsd.net, which is a wrong URL. Can I

Stemmer and Synonym analyzer

I am planning on building an analyzer that has stemming, stopwords and synonyms. I am planning on using the Snowball Porter stemmer and the WordNet synonym engine. Does it make sense to stem the synonym index? I do not want to stem the term “history” and then try to find the synonym. The st

If you were talking about a reasonably stable dataset e.g. products in a catalogue that would be manageable in Lucene because the volume of updates is comparatively low (one set of categorisations maintained by the site owner e.g. something like Cnet where Solr/faceted search came from). If you

Re: Lucene Queries Over User-Editable Dynamic Categories of Documents

Given the volatility in the set membership I'd be tempted to keep that grouping info in a database rather than doing the reader/writer-open/close dance in Lucene before you can see any updates. (I suspect this is the reason you've opted not to keep the info in Lucene). You can pull a user's list
