some of programs send direct queries google , parse html results - instance http://www.google.com/search?q=foobar&hl=en&num=20 . unfortunately, seems since recently, when sending such queries google, "num" parameter ignored because of instant search. no matter what, 10 results shown in page. if disable instant search, works again. problem settings stored in cookie or , it's impractical, if @ possible, pre-set program side. is there way add parameter query bypass instant search , "num" working again? i'm sure i'm not 1 parsing google html results... just add "&as_qdr=all" http://www.google.com/search?q=foobar&hl=en&num=2&start=0&as_qdr=all

for sequence of values, how 1 find sorted middle 50% of sequence in boost accumulators? for example, let's have following sequence, 25, 21, 9, 13, 17, 19, 12, 29, 50, 97, 10, 11 . the middle 50% data have follows: 13, 17, 19, 21 . of course, 1 can sort sequence, becomes 9, 10, 11, 12, 13, 17, 19, 21, 25, 29, 50, 97 . and 1 can collect middle 50% data. now, accumulators framework internally store , sort sequence? if yes, possible retrieve value reside in particular index? reading here , think accumulators framework not store original data , framework not appropriate problem trying solve. while writing this, find bit foolish try accomplish using accumulators. however, using other purposes , expecting solution in accumulators. now, possible build data structure efficiently maintain current , sorted middle 50% data in way size of data structure never exceeds half of size of sequence? thinking while, guess may not possible devise such data structure. @ first tho...
