Having common word in the search
Dear All Searcher searcher = new IndexSearcher(C:/index); Analyzer analyzer = new StandardAnalyzer(); String line=curry asia; line=line+recipe; String fields[] = new String[2]; fields[0] = title; fields[1] = contents; Query q = MultiFieldQueryParser.parse(line,fields,analyzer); Hits hits1 = searcher.search(q); In the above code Hits will return the documnet that contains the word 1)Curry OR asia OR recipe 2)Curry OR asia AND recipe 3)Curry AND asia AND recipe 4)Curry AND asia OR recipe But I want the result should be Like this 1)Curry AND asia AND recipe 2)(Curry OR asia) AND recipe My question is how to give the condition Actually my requirement is like this User will enter some text in text box it may be one word or two word or n word.(Eg curry asia) but when i am searching i will append recipe word in the search string so the search must contains recipe word. Finally search should contains 1)Curry AND asia AND recipe 2)(Curry OR asia) AND recipe search should not contains 1)Curry AND asia OR recipe 2)Curry OR asia OR recipe Thanks and regards Raju
Re: Logic of score method in hits class
I did in the same way what you mentioned i mean divide all scores by the first score and multiply by 100 Still I am not geeting exactly what I wanted. I am searching for two words asia cup in the search First three hits contains both words what i am searching for but i got percentages 100,69 and 33 respectively. I am using String fields[] = new String[2]; fields[0] = title; fields[1] = contents; Query q = MultiFieldQueryParser.parse(line,fields,analyzer); Hits hits = searcher.search(q); float sc = hits.score(i); Thanks in advance Raju - Original Message - From: Doug Cutting [EMAIL PROTECTED] To: Lucene Users List [EMAIL PROTECTED] Sent: Monday, July 26, 2004 11:37 PM Subject: Re: Logic of score method in hits class Lucene scores are not percentages. They really only make sense compared to other scores for the same query. If you like percentages, you can divide all scores by the first score and multiply by 100.

updating the index created for database search
Dear All I need help to update the index created for the database search I created the index with three field mapping to the three column of database(oid(primarykey),title, contents) Then I created the document for each row and added to the writer doc.add(Field.Keyword(OID,oid+)); doc.add(Field.Text(title,title)); doc.add(Field.Text(contents,contents)); writer.addDocument(doc); Here search is only on title and the contents and oid is the key to retrieve the details from the database. Later if the contents column in the database is updated. We have to updated the content in the index also If I use the writer with false IndexWriter writer = new IndexWriter(C\index, new StandardAnalyzer(),false); then all the record are inserted in to index without deleting the old index causing duplication If I use the writer with true IndexWriter writer = new IndexWriter(C\index, new StandardAnalyzer(),false); then record are inserted in to index deleting all the old index. My question is 1) How to update the existing index 2) When I fetch the rows from the database in order to update or insert in index how to know which record is modified in database and which record is not present is index Thanks is advance Raju

Re: updating the index created for database search
Dear Daniel Thanks a lot. I do have the last-modified column in my database. But how to know how many records are modified. If it is new record through which class we have to check that record is present in the index In the mean time I will look into IndexHTML in lucene demo Regards Raju - Original Message - From: Daniel Naber [EMAIL PROTECTED] To: Lucene Users List [EMAIL PROTECTED] Sent: Monday, July 26, 2004 3:35 PM Subject: Re: updating the index created for database search On Monday 26 July 2004 11:37, lingaraju wrote: 2) When I fetch the rows from the database in order to update or insert in index how to know which record is modified in database and which record is not present is index Your database will need a last modified column. Then you can select those rows that have been modified since the last update and for each row check if it's in the Lucene index. If it is, delete it there and re-add the new version. If it's not, add it. To delete documents you will probably need to iterate over all your IDs in the Lucene index and check if they are still in the database. If that's too inefficient you could check if you can do it the way the file system indexer (IndexHTML in Lucene's demo) does it. BTW, please don't cross-post to both lists.
