Hi,all Maybe lots of u guys have used google mail. i noticed google mail has a good feature called labels. you could select a mail then just put labels on it by select <more actions>-><apply label>. The labels could be created by users dynamicly . Then you could list your mails just by these labels, very fast. And one mail could have more than one label.
I always wondering how google did this. considering the mail amont this must be a search technology. Can Lucene also implement the same function by now? i have thought about this but got no solution. :( So i wrote this mail, if anyone have good suggestions i'll appreciate it very much. Richie
