Hi, I am getting this error when accessing my index with Luke. No sub-file with id _1.f0 found Does any one have idea about this?? Any help would be appreciated. Thanks, -Vasu - Stay in the know. Pulse on the new Yaho

Parameterized IndexModifier

Hi, The IndexModifier class always opens up an IndexWriter in the init method. If we need to update a document, it closes the IndexWriter and opens up IndexReader to delete the desired document. Then again it opens IndexWriter to add the document to the index. Instead can't we pass one extra

PrefixFilter Memory Consumption

Hi, Can anyone please tell as to what is the difference between PrefixFilter and WildcardQuery as far as memory is concerned? I saw the code of PrefixFilter and it gets TermEnum for all the terms in the index. Won't this consume memory?? I started using PrefixFilter, ConstantSc

(Term term = null; (term = wildEnum.term()) != null; wildEnum.next()) { termDocs.seek(term); while (termDocs.next()) { bits.set(termDocs.doc()); } } return bits; } } Hope this helps Erick On 10/16/06, vasu shah wrote: > > Hi, > > I have have multiple fields that I need to search o

PrefixFilter and WildcardQuery

Hi, I have have multiple fields that I need to search on. All these fields need to support wildcard search. I am ANDing these search fields using BooleanQuery. There is no need for score in my search. How do I implement these. I have seen PrefixFilter and it sounds promising. But then how do I

Indexmodifier optimize

Hi, I added one record to the index and did flush(), optimize() and close() in that order. I had one index file _twca.cfs. After the inserting the document and doing optimization, I have two index files _twca.cfs and _twcf.cfs (both approx. same size) and deletable file having entry for _twc

Modify index on database update

Hi, My application database can be updated outside the application also. Whenever there is a change in database by some other source, I want to update my index. Is there any way to do so? I am using Java and the database is DB2. I saw the DB2 UDF. But I have to put the jar insid

Re: IndexReader / IndexWriter Synchronization

Thanks Mike for the reply. I will look into Lucene in Action. I am not very good at threading. So I was looking if there is any api class (even in nightly builds) on top of the IndexReader/IndexWriter that takes care of concurrency rules. Every developer must be facing this problem o

IndexReader / IndexWriter Synchronization

Hi, I went through the IndexModifier class. It says that - Although an instance of this class can be used from more than one thread, you will not get the best performance. You might want to use IndexReader and IndexWriter directly for that (but you will need to care about synchronization y

Thank you very much for the quick response. I was just a little skeptical about Lucene for my application. This user forum is really supportive by posting the replies immediately. Thanks, -Vasu karl wettin <[EMAIL PROTECTED]> wrote: On Sun, 2006-07-23 at 14:44 -0700, vas

How reliable is lucene indexing !!

Hello Everyone, We have an application and the current search is taking lot of time to return the results. We are doing a search against 8-9 database tables and 1.5 million records. I want to increase the search speed and thinking of implementing lucene search. I went through the documentation
