Hi all,
I'm new to solr so please let me know if there is a more appropriate place
for my question below.
I'm noticing a rather unexpected number of results when I add more keywords
to a search. I'm listing below a example (where I replaced the real keywords
with placeholders):
keyword1 851 hits
keyword1 keyword2 90 hits
keyword1 keyword2 keyword3 269 hits
keyword1 keyword2 keyword3 keyword4 47 hits
As you can see, adding k2 narrows down the amount of results (as I would
expect), but adding k3 to k1 and k2 suddenly increases the amount of
results. with 4 keywords, the results have been narrowed down again. Would
solr/lucene search algorithm with multiple keywords explain this non
consistent behavior? I would think that adding more keywords would narrow
down my results.
I'm pasting below the relevant log in case it helps:
INFO: [] webapp=/solr path=/select/
params={spellcheck=true&facet=true&facet.mincount=1&facet.limit=20&spellcheck.q=keyword1+keyword2+keyword3+keyword4&
json.nl=map&wt=json&version=1.2&rows=10&fl=id,nid,title,comment_count,type,created,changed,score,path,url,uid,name&start=0&facet.sort=true&q=keyword1+keyword2+keyword3+keyword4&bf=recip(rord(created),4,10704,10704)^200.0&facet.field=im_cck_field_author&facet.field=type&facet.field=im_vid_1=&indent=on&start=0&version=2.2&rows=10}
hits=10704 status=0 QTime=1
any hint on whether this is expected or not appreciated.
Steph.
