Re: Modelling relational data in Lucene Index?

Hi, I am actually doing something what the original poster mentioned. Previously, I have use Hibernate and Lucene. But I found that for my particular project my data is quite flat, so in the next version I totally take out Hibernate (and the complexity with it :)) and use Lucene as the "main stor

idf in scores

I've been trying to understand how idf is arrived at from a query. I have a single Document with 9 fields. One field "subject" has the phrase "RFC2822 - Internet Message Format" and a second "body" has the contents of rfc2822. The other fields contain additional meta data. If I search for su

Hi Chris, My scenario is: I will key in the first search value in the text box, then the first search result will be return. Next, I will clear the first search value and key in the second search value within the same text box. The 2nd search value will search the first result, for inst

[sorry for the long delay for my answer, we are having some issues with our mail server...] Thanks for your comment. Yes it would make sense if the log files were not so big. In fact, I'm only indexing a subset of the log information. Because I store the information in Lucene, it is easier and f

Doc classification / categorization with Lucene ?

Hello, What are the best practices for document classification / categorization using Lucene? Any recommendations as far as manual vs. automatic, which products to use or not to use? Does Lucene offer anything out of the box? Thanks, - Dmitry

Any profiler can add it's own overhead. You might try the "-verbose:gc" JVM flag (if you haven't tried it yet). The fastest way to check if you problems are GC related. Check JVM docs (or plainly - 'java -help' for more flags. There are some '-X' flags for more detailed info, as well as flags to du

So, if I'll be using Solr, what's the right strategy? Is it possible to redefine SolrDocument class through configuration? If not, would it be safe to inject these properties through Aspects while maintaining the whole framework intact and in workable condition? (eg, if at some point for some reaso

Re: Modelling relational data in Lucene Index?

I had a quick look at SOLR and DBSight. They seem to achieve a different goal than Hibernate Lucene. The formers belong to the project box category: you set up a server that will handle the search for you. The application will then delegate the work to those servers. The latter belongs to the fr
