I have title field and description field indexed. Now I want to search for "object oriented programming" either in title "and or" description using Lucene search query. How do I do this? - To unsubscribe, e-mail: [EMAIL PROTECT

Re: multiple tokens at the same position

Another (obvious) option is to use two indexes and direct the query to the appropriate index depending on the search specification. Of course you double your space requirements, but your basically going to do that anyway if you use two fields. I chose this for the slight benefit of fewer fields on

Re: Scoring on Number of Unique Terms Hit, Not Term Frequency Counts

I know you have a solution already that I agree with, but I do think the DisjunctionMaxQuery could serve as the start for writing your own Query that did what you want. Why would you want to? Well, maybe you have other ways you want to search as well and don't want to mess with custom Sim

Indexing help needed

I've been working on this for a while, I am trying to get the demo code that comes with Lucene to index OpenOffice documentss. I've looked at LIUS code and at Nutch code. But can't find an easy way. So I am digging into the code. I wrote a KcmiDocument class that returns a Document. In it I

Re: multiple tokens at the same position

I can only speak to the " avoid matching stemmed or canonical forms" part... Yes, but you've got to do some fancy dancing when you index, something like adding a special signifier to, say, the original token. I'll ignore the canonical part of your question for the sake of brevity. Consider inde

Re: Setting the maximum number of documents in a lucene segment

Hello Ard, What you are after is a higher mergeFactor and probably also a higher maxBufferedDocs. Is indexing performance the concern? Don't go crazy with setting a super high (e.g. 100+) mergeFactor, unless you really have the number of open files on your server(s) set to a solid/high number.

multiple tokens at the same position

Hi, In nutch we have a use case in which we need to store tokens with their original text plus their stemmed form plus their canonical form(through some asciifization). From my understanding of lucene, it makes sense to write a tokenstream which generates several tokens for each "word", but p

Setting the maximum number of documents in a lucene segment

Hello, I am trying to change the maximum number of documents in a lucene segment. By default it seems to be 10. When I have a mergeFactor of say 10, then on average, after every 100 added documents lucene is merging segments. I want each segment to contain more then the default 10 documents, be
