Range queries

Two queries about ranges: 1. field:[a TO z] does not return the same as field:[z TO a] I think it should. The standard QueryParser or even the range query should ascertain the lowest and highest and switch them around if necessary 2. How do I search for negative numbers in a range. For example

Selecting the maxium/highest numerical value from a lucene Index)

Hi A database is used as our primary data store. Our lucene index is then created and updated from this database. We store the value of the database primary key in the lucene index as we need to be able to identify documents across the database and lucene index. New documents are inserted into

RE: Selecting the maxium/highest numerical value from a lucene Index)

I'm only a novice at these things but if I had to do that right now? I'd add a document that represents that primary key with a value representing the next available number and everytime I go to do some additions I'd get it, use the value and then delete and re-add that document with the revised ne

OutOfMemory during optimize

Boost value and LUKE

Hello All, I am testing the boost value within the latest version of Lucene and I'm inspecting the results through Luke. For each FIELD that I want to boost I use the setBoost method. And everything looks good. But Luke is refusing to exposure the boost value and keeps returning 1.0 for th

RE: Boost value and LUKE

I'm pretty sure this is a bug or incompatibility with Luke - I'm using boosted documents, and I seem to remember that Luke reported everything as 1.0, even though my test applications showed things correctly. The boost in the final app is working fine, so the functionality of Lucene appears to be

Re: Boost value and LUKE

Eh, I did some some tests after I sent the email to see if I was doing it right and they confirmed your results. The scores were higher for boosted content. Thanks for the reply [EMAIL PROTECTED] wrote: I'm pretty sure this is a bug or incompatibility with Luke - I'm using boosted document

Hi Otis, sorry if I posted to the wrong group. I though user was for usage-type queries and dev was for development-type queries. As I was asking about changing the code itself (rather than about interfacing with it) I assumed this was a dev forum issue. I'm still a bit confused.. can you tell me w

RE: Boost value and LUKE

Ah - that's useful to know. Although in that case I'd suggest that the sensible thing for Luke to do would be to either remove the boost field, or show it as "unavailable", instead of (misleadingly) displaying it as 1.0... Cheers, Tim. -Original Message- From: Andrzej Bialecki [mailto:[

Re: Boost value and LUKE

Eh yeah. I remember reading that. The boost is calculated at indexing time. That didn't even click. Thanks. Andrzej Bialecki wrote: [EMAIL PROTECTED] wrote: I'm pretty sure this is a bug or incompatibility with Luke - I'm using boosted documents, and I seem to remember that Luke reported e

Re: Selecting the maxium/highest numerical value from a lucene Index)

: What is the easist way to identify the maximum or highest primary key : value in the lucene index? The most straight forward way is to do a search for all documents, ordered by the field you are interested in, and then get the value out of hte first document. Under the covers, sorting works us

performance implications for an index with large number of documents.

Hi, Apologies if this question has being asked before on this list. I am working on an application with a Lucene index whose performance (response time for a query) has started degrading as its size has increase. The index is made up of approximately 10 million documents that have 11 fields. Th

Re: performance implications for an index with large number of documents.

Lucene scales with the number of unique terms in the index and not the number of documents nor the size of the documents. Typically, you should have at most 1 million unique terms for a set of 10 million documents. So the fact that you have 13 million unique terms in 10 million documents tells me
