Good example scientific lucene sites?

Hi, I'm going to be demonstrating some of our work with lucene to a prospective customer this week, and I'm wondering if any of you have suggestions for other relevant sites that use lucene. In particular, I'm interested in scientific or technical sites, perhaps with use of the highlighter, and per

Re: Faster highlighting with TermPositionVectors

Hi, We are very interested in highlighting, but haven't gotten around to reviewing the state of the highlighting mechanisms. Could someone possibly give me the "big picture" on highlighting? What code is available? How does it work? What are the current issues? Many thanks, Fred At 07:16 PM 10/28/2

Re: Index + Searching

direction that would really be appreciated. I am thinking about editing the shipped HTMLDocument.java and HTMLParser.java files but not sure what I need to add. Can you please explain a little more. TIA. -H Fred Toth wrote: Hi, Could be your best bet is to use HTML tags. Create tags for name, description,

Re: single quote unicode character

Hi Chris, Getting unicode to pass cleanly through to the browser can be tricky. A couple of questions: What do you see instead of the incorrect character? What happens when you tell your browser to display UTF-8? (In IE, it's in View->Encoding->Unicode) Does your character display properly? Are you

Sorry, that didn't cure it. Again, anyone want to point me to the quickest replacement HTML parser (that's unicode clean)? Thanks, Fred At 03:17 PM 9/24/2004, you wrote: On Friday 24 September 2004 19:58, Fred Toth wrote: > I've got unicode in my source HTML. In particular, withi

demo IndexHTML parser breaks unicode?

Hi, I was hoping it wouldn't come to this: I've got unicode in my source HTML. In particular, within meta tags, and it's getting broken by the indexer. Note that I'm not trying to query on any of this, just store and retrieve document titles with unicode characters. Has anyone else experienced this

Keyword query confusion

Hi all, I'm trying to understand what's going on with the query parser and keyword fields. I've got a large subset of my documents which are "publications". So as to be able to query these, I've got this in the indexer: doc.add(Field.Keyword("is_pub", "1")); However, if I run a query: is_pu

demo HTML parser question

Hi, I've been working with the HTML parser demo that comes with Lucene and I'm trying to understand why it's multi-threaded, and, more importantly, how to exit gracefully on errors. I've discovered if I throw an exception in the front-end static code (main(), etc.), the JVM hangs instead of exiting

indexes won't close on windows

Hi, I have built a nice lucene application on linux with no problems, but when I ported to windows for the customer, I started experiencing problems with the index not closing. This prevents re-indexing. I'm using lucene 1.4.1 under tomcat 5.0.28. My search operation is very simple and works great:
