But,what is it funtion? why is it so
important?<br> Another confusion is about Valuerangeprocess. I really want to make clear <br>differences between valuerange-search and common search in details. I added <br> Xapian::DateValueRangeProcessor date_proc(2, true, 1930); <br> qp.add_valuerangeprocessor(&date_proc); <br>in my code and my code works well. then, I debug it using gdb. however,i can not be
inspired. Is there any important information i did not catch?<br><br>would you please give me some advice?<br><br>thanks a lot!<br><br>baijl<br></b></td></tr></tbody></table><a rel="nofollow" target="_blank" href="http://cn.rd.yahoo.com/mail_cn/tagline/card/*http://card.mail.cn.yahoo.com/"></a></div></blockquote></td></tr></table><br>
