Re: search exception in servlet!Please help me

By observing the implementation details of the Hits object lucene, I feel that Hits.doc(n) intends 'n' to be the index of the results. So, my feeling is that progam which Li wrote should work ideally. Erik, Correct me if I am wrong. Li, Can you post entire stack trace? Thanks, sri hi,Erik

Erik Hatcher wrote: Where did you get 'i'? Keep in mind that using Hits.doc(n) intends 'n' to be a document *id*, not the iteration through the Hits collection. This is a very common mistake, and I'm guessing one you've made here. I believe the Javadoc (as well as my own experience) tells

You could instead use a HitCollector to gather only documents with scores in that range. Doug Karthik N S wrote: Hi Apologies If I want to get all the hits for Scores between 0.5f to 0.8f, I usally use query = QueryParser.parse(srchkey,Fields, analyzer); int tothits =

Question on number of fields in a document.

Hi I had a question related to number of fields in a document. Is there any limit to the number of fields you can have in an index. We have around 25-30 fields per document at present, about 6 are keywords, Around 6 stored, but not indexed and rest of them are text, which is analyzed and

Re: Negative Boost

Near as I can tell, setting the boost to, say, 0.10, doesn't seem to do anything. Regards, Terry - Original Message - From: Otis Gospodnetic To: Lucene Users List Sent: Wednesday, August 04, 2004 9:38 AM Subject: Re: Negative Boost You can just use boost that is 1.0,

Re: Negative Boost

Well, I'm not too confident of my JavaCC skills, and when I've messed around with this stuff in the past, I sometimes ended up inadvertently creating problems in other areas of the query syntax. But if, in the future, I or someone else took on this task of enhancing QueryParser, I'd like to

Question on the minimum value for DateField

Hi All, I realize that the DateField cannot except the value which is before the Year 1970, specifically in the org.apache.lucene.document.DateField.timeToString() method. Is there are any techincal reason for this limitation? Thanks, Terence

Re: Question on number of fields in a document.

Thanks I was looking at some older email on the list and found an email where Doug Cutting says that fields not analyzed, we need not store the norms , nor load them into memory. That change in the indexer will help a lot in this situation, where we might have 24 fields indexed but not

Split an existing index into smaller segments without a re-index?

Is it possible to take an existing index (say 1G) and break it up into a number of smaller indexes (say 10 100M indexes)... I don't think theres currently an API for this but its certainly possible (I think). Kevin -- Please reply using PGP. http://peerfear.org/pubkey.asc
