Re: Possible bug in QueryParser when using CJKAnalyzer (lucene 2.4.1)

I'm not sure this is the same case, but there is a report and patch for CJKTokenizer in JARA: https://issues.apache.org/jira/browse/LUCENE-973 Koji Zhang, Lisheng wrote: Hi, When I use lucene 2.4.1 QueryParser with CJKAnalyzer, somehow it always generates an extra space, for example, if the

Possible bug in QueryParser when using CJKAnalyzer (lucene 2.4.1)

Hi, When I use lucene 2.4.1 QueryParser with CJKAnalyzer, somehow it always generates an extra space, for example, if the input is "ABC", the query would be: myfield"AB BC " // should be myfield:"AB BC" If I create PhraseQuery directly it does work. From Luke I know indexing works OK. In lucene

Re: Searching documents that contain a field (text of field is irrelevant)

Couple of approaches. (But not very sure if there are other better approaches) 1. Add a seperate field which is set to 1 or 0 depending upon if the self description is present or not. Then you can search by this new field. 2. Along with each self-descrition add a common idenfier word. Then you ca

Searching documents that contain a field (text of field is irrelevant)

Hey! Consider a bunch of documents that represent, say, students. These students have the following attributes: 1) Student IDs 2) Name 3) Self-description (optional) So, all documents have id: and name:, but only some of the documents have an added desc: Assuming all of the fields are indexed,

Has anyone used Katta in production? It looks very interesting and feature-rich, but I'm wondering how stable it is and whether or not it can support fine-grained queries - for example, constant score queries, MultiSearcher, etc. -Original Message- From: Ken Krugler [mailto:kkrugler_li...

Question on Efficient field updates in the Lucene index in Nutch

Re: Sorting fields while searching!

It's really unclear to me what PhysicianFieldInfo.FIRST_NAME_EXACT.toString() returns. I assume the intent is to return a field name, but how that relates to FIRST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED) doesn't mean anything to me. Could you provide some details? Note that if you s

Sorting fields while searching!

I have two fields initialized following way for Index writing: FIRST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED), LAST_NAME_EXACT(Field.Store.YES, Field.Index.UN_TOKENIZED), I have a prefix query to look for any name starting with the name entered by the user. Lets say user enters 'kar

Just build your own. Here's exactly what you are looking for: (Mind you I just whipped this out, and didn't compile it... so there could be minor syntax errors here.) You will also obviously have to make your own package declaration, and your own imports. So anyhow, the really neat thing a

Re: No hits while searching!

Thanks Matt & sithu. Yes, It was due to stop word analyzer...now i'm using a simple analyzer temporarily, as I know even simple analyzer cannot handle quotes in names. However, can somebody plz direct me towards how to handle quotes with the name in query using lowercase analyzer? thanks, Vanshi

Lucene on NFS/iSCSI

So I've read a lot about nightmares with lucene over shared indices using NFS, and was curious if anyone had any experience running Lucene over iSCSI? Specifically if the same sort of lock failure issues occur as does with NFS. I'm specifically looking into multple machines mounted to a SAN v

Re: No hits while searching!

Yeah, he's gotta be. You might be better of using something like a lowercase analyzer here, since punctuation in a name is likely important. Matt Sudarsan, Sithu D. wrote: Do you use stopword filtering? Sincerely, Sithu D Sudarsan -Original Message- From: vanshi [mailto:nilu.tha
