I'm still working on my own fix for this date-sorting stuff :-)
I'm working with an index of about 12000 pages. I want to sort them by
date since it concerns the pages of a newspaper :-)
So, I used Gilles' patch (in combination with snapshot 111598).

Size.. 47M (!) ....... free...632K ... *wowie* This happened when I tried
to retrieve ALL documents from the database. (12000). Htsearch isn't able
to sort this much results on date.
I think time_t (anyway, compareTime) is the problem.
BTW, I pressed CTRL-C when it reached 47M... I'm sure htsearch would
result in a core-dump otherwise too...
When I use htsearch off the prompt, it asks me a 'value for sort'. When I
use 'date' and I search on something what should return about 40
results, htsearch DOESN'T sort on date! (Does this have to do with the
snapshot release I use?)
ResultMatch **array = new ResultMatch*[numberOfMatches];
+ if (numberOfMatches>1000) numberOfMatches=1000;
+ for(j=0; j < numberOfMatches; j++)
qsort((char *) array, numberOfMatches, sizeof(ResultMatch *),
Display::compare(const void *a1, const void *a2)
/* I use this to sort on date.. don't care about Scores or so...*/
ResultMatch *m1 = *((ResultMatch **) a1);
ResultMatch *m2 = *((ResultMatch **) a2);
time_t t1 = m1->getRef()->DocTime();
struct tm *tm1 = localtime(&t1);
time_t t2 = m2->getRef()->DocTime();
struct tm *tm2 = localtime(&t2);
I know this is an ugly piece of code :-) Don't bother me with that!
What I do here is (maybe stupid) as follows: I take century and
number_of_day_of_the_year. (1998364 for example). Gilles' patch is
better on this I suppose..
Using the routine above, I'm able to QUICKLY sort about 1000 documents by
date. Therefore, I have to build a limit in htsearch so that it can only
display 1000 matches, even if it found 12000...
The 1000-limit is because time_t eats to much mem (not really sure, but
when I comment it out htsearch doesn't give me a core-dump)
HtDig is great :-)
