Hoss: It was late this afternooon and I was square-eyed, so I didn't add the detail. The app we're working on first returns a summary list of all the books that match a query, no hit information. Next, the user clicks on a returned title and we show the hits by chapter. That is, a list of chapters and the count of the hits for each. The index is nearing 15G at present, so I *assumed* that I really didn't want to re-query the entire index when I know the particular document I care about already. But what do I know?
Mark: Very most excellent. I'll give it a look in the morning. I hope that the class doesn't need the raw text since I don't have it any more, but your comment "Give it a query it will give you the spans" makes me hopeful. The real issue is that it looks like I'm reverting to my old "C" days. The code I was writing the last couple of days started to look like a program from...well...a long time ago. So I *know* it must be wrong <G>...... It's a real pain in the neck to *think* in Java terms when much of my training was before this new-fangled way of looking at programming problems happened. I suppose I could go into management, but that would be giving in to the dark side.... Thanks all Erick On 1/18/07, Mark Miller <[EMAIL PROTECTED]> wrote:
Just threw together a highlighter that can handle spans (combining a rewrite with dumspans from LIA) and used this: http://issues.apache.org/bugzilla/attachment.cgi?id=15568 Nice spans extractor from Mark (not me <G>).
