If you wont to index Hibernate persisted data, just use Compass. M.

Re: search through all fields
Compass doesn't index database, but pojo mapped with an orm. Parent relation is nice handled. When a pojo is persisted, compass catch the information and index/ remove it with lucene. There is some troubles when you change something related to a pojo. Compass doesn't see that change. They were some works for that, just have some try to see if it's works, now. http://www.opensymphony.com/compass/versions/1.2M2/html/index.html M.

Questions about Query's Idf and NEW Similarity fomula. Thanks!
Nowadays, I’m doing research using the lucene to build the prototype. I have read the book “Lucene in Action”, but can’t find the solution, so I try to beg for your help. I have 2 questions: 1) I found that the term in query doesn’t use the idf but only tf, however, in my application I have many queries and it will be inaccurate regardless idf. My prototype will establish the traces between two kinds of document, so the idf of the query is also important, could you give some advices? 2) I try to use the WordNet to associate words, however, lucene provides synonymy approach which considers the similarity between word “seek” and word “search” is 1. In my research, I will consider the similarity coefficient between words ranges from 0 to 1, and I revise the similarity formula. I don’t know where to insert my formula into lucene.

CJKAnalyzer - Issues with scoring
Hello, I am in desperate need of help on a problem with our newly deployed application that is now using the CJKAnalyzer/CJKTokenizer. Our previous release was using the WhitespaceAnalyzer and the users were extremely happy with the search results ordered by the score of the documents. We switched to the CJKAnalyzer and now the scoring is not giving them the results they are expecting. Any ideas on why using the CJKAnalyzer would be so different? Some documents that contain more instances of a search term are appearing at a lower position in the search results than those having one instance of the search term. I tried printing the explanation of the scoring but don't get any information, just the value 0.0 for each doc returned. Anyone have any ideas? I have not dug deep into this problem. I am pressed for time so was hoping someone could provide some guidance. Thanks!! Nina

Re: CJKAnalyzer - Issues with scoring
Sure. It is one of the contributed analyzers. The Java docs are here: http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/index.html. Also, the source files are here: http://svn.apache.org/viewvc/lucene/java/trunk/contrib/analyzers/src/java/org/apache/lucene/analysis/cjk/ Thanks, Nina "Dmitry" <[EMAIL PROTECTED] mail.com> To 07/22/2007 10:44 cc PM Subject Re: CJKAnalyzer - Issues with Please respond to scoring [EMAIL PROTECTED] apache.org Nina, can you point me to the link where I can get documentation about CJKAnalyzer. thanks, DT www.ejinz.com Search Engine Economy - Original Message - From: "Nina Khosravi" <[EMAIL PROTECTED]> To: Sent: Sunday, July 22, 2007 11:38 PM Subject: CJKAnalyzer - Issues with scoring Hello, I am in desperate need of help on a problem with our newly deployed application that is now using the CJKAnalyzer/CJKTokenizer.

Re: CJKAnalyzer - Issues with scoring
Hello, I actually found an error in my code. Thanks to anyone taking a look at this but the way I was setting the "score" sort field had an error. Sorry about this. Thanks, Nina
