Document boost not applied to numeric fields

belevian · December 27, 2011, 5:21pm

Hi all,

I am experimenting a strange behaviour with ES for document boosting
on numeric field.

I have created a gist to present my problem :

gist.github.com

https://gist.github.com/belevian/1524253

gistfile1.sh

#######
# creation of an index foo
#######

curl -XPUT 'http://127.0.0.1:9200/foo/?pretty=true' -d '
{
  "index" : {
    "number_of_shards" : 1,
    "number_of_replicas" : 0
  }

This file has been truncated. show original

It seems that the document boost is not working for search based on
numeric fields only.

Maybe It is related to this issue :

I dont know if It is a bug in ES or a limitation in Lucene.

Do you have any solution better than to index my numeric field as
string field with a not_analyzed setting or to add a match_all
subquery with a norms_field setting in my search query ?

Thanks in advance for your answers.
