[Xapian-discuss] Relevance wdf

[roki roki]

Hi there,

I am trying to use Xapian in combination with Perl but I have some
difficulties with sorting results.
I am adding postings with wdf number which depends on position and format of
term eg $doc->add_posting("marketing", 1, 50); 
When i search for "marketing" i expect that document with biggest wdf come
as first but it does not work this way. 

delve ... -v  -t marketing.|head  produces:
1 447 11332
2 492 17863
3 268 5452
4 403 6768
5 448 9542
6 358 10792
7 362 6191
8 675 12712
9 311 7547
10 384 9814
11 316 6588
12 2306 160980
13 2038 118782
14 313 6509
15 490 10720
16 268 5167
17 537 12958
18 314 8072
19 317 7535
20 401 10683
21 316 4225

so I except to see as results
12
13
8
17
..

but i get as result:
ID 8 100%
ID 17 99%
ID 15 99%
ID 13 99%
ID 5 99% 
ID 1 99% 
ID 12 99%
ID 4 99% 
ID 2 99% 
ID 20 99%
ID 10 99%
ID 7 99% 
ID 6 99% 
ID 19 99%
ID 11 99%

Is it possible that get desired result with Xapian?

Thanks!
Roki
