Unable to get function_score to work

Srinivasan_Ramaswamy · April 3, 2014, 8:03pm

Hi

I just started playing around with elastic search and I am trying out the
examples in the website with my data. I am trying to get custom scoring
working. I am following the example from
http://www.elasticsearch.org/guide/en/elasticsearch/reference/1.x/query-dsl-function-score-query.html
But unable to get the example working

{
"query" : {
"function_score": {
"boost_mode": "replace",
"query": {"design.PRODUCT_DESC":"cool"},
"script_score": {
"params": {
"param1": 2,
"param2": 3.1
},
"script": "_score * doc['design.CLICKS'].value / pow(param1,
param2)"
}
}
}
}

I tried this query and i get the error

Caused by: org.elasticsearch.index.query.QueryParsingException: [designs]
[_na] query malformed, no field after start_object

at
org.elasticsearch.index.query.QueryParseContext.parseInnerQuery(QueryParseContext.java:216)

at
org.elasticsearch.index.query.functionscore.FunctionScoreQueryParser.parse(FunctionScoreQueryParser.java:89)

at
org.elasticsearch.index.query.QueryParseContext.parseInnerQuery(QueryParseContext.java:223)

at
org.elasticsearch.index.query.IndexQueryParserService.parse(IndexQueryParserService.java:330)

at
org.elasticsearch.index.query.IndexQueryParserService.parse(IndexQueryParserService.java:260)

at
org.elasticsearch.search.query.QueryParseElement.parse(QueryParseElement.java:33)

at
org.elasticsearch.search.SearchService.parseSource(SearchService.java:622)

Any help would be appreciated.

Thanks
Srini

Hi Srinivasan,

It seems your intern "query" is malformed. Try this:

{
"query": {
"function_score": {
"boost_mode": "replace",
"query": {
"match_all": {}
},
"script_score": {
"params": {
"param1": 2,
"param2": 3.1
},
"script": "_score * doc['design.CLICKS'].value / pow(param1,
param2)"
}
}
}
}

Cheers,
Luiz Guilherme

Thanks Luiz, that was really helpful The examples in the guide could be
made more helpful. After you pointed out the the location of the error I
got it working with

{
"query": {
"function_score": {
"boost_mode": "replace",
"query": {
"match": { "design.PRODUCT_DESC":"cool"}
},
"script_score": {
"params": {
"param1": 2,
"param2": 3.1
},
"script": "_score * doc['design.CLICKS'].value / pow(param1,
param2)"
}
}
}
}

Thanks
Srini
