Does this mean my impression that my boolean queries "just don't work" is correct? I seem to always be retrieving half of what I thought I should. Oh, BTW: You're disipline is trivial - given unlimited CPU-power, unlimited bandwidth, and unlimited manpower to implement the solution, I'm quite certain I could make something much better than what is available today ;-) (The IR-model I hope will be able to interface-wise cope with large information spaces is a projection of a multi-variate analysis space, where you initially go by categories/keywords, and then do space-manipulations when you're somewhere in the vicinity of your target. Did I remember to repeat the 'unlimited resources' part?) Eivind. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-database" in the body of the message
