Re: Lucene

Hi, Devinder, Lucene is agnostic of any database configuration. You need to pull data via jdbc out, and feed it to Lucene to create an index file, and then use Lucene API to search on it. -- Chris Lu - Instant Scalable Full-Text Search On Any Database/Application site: ht

Ivan - have you considered using NumberUtils? I'm curious if those utility methods solve the same problem you're working on. Erik On Sep 13, 2007, at 1:19 PM, I

Re: search results with sort

Hi, Thanks. However, I tested with more terms in title field, for instance, lucene sort, abc_def, and that works. I deleted the old index file and re-index the whole documents again, and it works fine. So, I'm little bit confuse about how that really work. Please advise. -- View t

I'm not entirely sure. So what I'd do if I were you is write a little test program and step through it in the debugger and see But, if you're only allowing the user to fetch a single document at a time, I don't think it matters enough to worry about. If, on the other hand, you're allowing the

Treating values of numeric fields as numbers

Hi All, I have made some changes in my Lucene source, so that values of numeric fields to be treated as numbers but not as Strings. After testing everything seems to work correctly, but I still would like to know your opinion about this. So my approach is the following: 1. As during the inde

Also, ensure that you didn't inadvertently add an older version of your Jar file somewhere in your classpath. Eclipse will take the first it comes to, and skip any others found later on in the path. Right Click on your Project -> Properties -> Java Build Path and ensure you don't have an olde

It sounds like there may be a Lucene version mismatch? When Luke was used it was likely based on Lucene 2.2, but it sounds like an older version of Lucene is now being used to open the index? Mike "testn" <[EMAIL PROTECTED]> wrote: > > Should the file be "segments_8" and "segments.gen"? Why is

well, actually, I have 5 index directory and it will increase in future. and the thing is that each document about 20 fields on average. considering many users may connect to the system (we anticipate 500 users at this time) I want to know whether this will make performance issue or not. we provi

Re: regarding FieldSelector

Do you have any evidence that you're having a performance issue? If not, I'd just do the simple thing and ignore the rest. The performance issues I found were because I was spinning through many, many documents. If you're only worrying about one document at a time, it may not be an issue. If you *

Re: Tokenization question

If I'm understanding you correctly, the answer is... maybe, kinda. Take a look at some of the Luke code. That tries to reconstruct document fields from the index, but it's lossy. So it depends upon what kind of fidelity you need. Erick On 9/12/07, Dan Luria <[EMAIL PROTECTED]> wrote: > > If I hav
