Hi!

I'm trying to get field level boosting to work and have run into some  
problems.

I have set this mapping:

curl -XPUT '[http://localhost:9200/test/doc/\_mapping](http://localhost:9200/test/doc/_mapping)' -d '  
{  
"doc": {  
"name": "\_boost",  
"null\_value": 1  
},  
"val1" : {  
"type": "string"  
},  
"val2" : {  
"type": "string"  
}  
}  
}'

and the following documents:

curl -XPUT '[http://localhost:9200/test/doc/](http://localhost:9200/test/doc/)' -d '  
{  
"val1": {  
"\_value": "foo",  
"\_boost": 2.0  
},  
"val2": {  
"\_value": "bar",  
"\_boost": 1.0  
}  
}'

curl -XPUT '[http://localhost:9200/test/doc/](http://localhost:9200/test/doc/)' -d '  
{  
"val1": {  
"\_value": "foo",  
"\_boost": 1.0  
},  
"val2": {  
"\_value": "bar",  
"\_boost": 2.0  
}  
}'

curl -XPUT '[http://localhost:9200/test/doc/](http://localhost:9200/test/doc/)' -d '  
{  
"val1": {  
"\_value": "foo",  
"\_boost": 3.0  
},  
"val2": {  
"\_value": "bar",  
"\_boost": 2.0  
}  
}'

When doing the search:  
curl -XGET '[http://localhost:9200/test/doc/\_search?q=val1.\_value:foo](http://localhost:9200/test/doc/_search?q=val1._value:foo)'

I expect to get the last document withe the highest score,  
followed by the fist document and the second document to be inserted. But  
instead i get the same score on all three documents. What am I doing wrong?

I'm using ElasticSearch 0.20.4 - 2013-01-29.  
Found this ([https://github.com/elasticsearch/elasticsearch/issues/920](https://github.com/elasticsearch/elasticsearch/issues/920)) but  
it seemed to be implemented 2 years ago, so it should work in this version?
