Hi.
I want to use custom score query for my scoring.
I am creating a new type script in index.
curl -XPUT localhost:9200/twitter/script/1 -d ' {"user" : 1}'
Now my custom query is
curl -XGET localhost:9200/twitter/script/\_search?pretty=true -d '
{
"query":
{
"custom\_score" : {
"query" : {
"match\_all" : {}
},
"script" : "\_score \* doc['user']"
}
}
}'
It throws error as
QueryPhaseExecutionException[[twitter][2]: query[custom score
(ConstantScore(_:_),function=org.elasticsearch.index.query.xcontent.CustomScoreQueryParser
$ScriptScoreFunction@13ff9d4)],from[0],size[10]: Query Failed [Failed
to execute main query]]; nested: CompileException[[Error: No field
found for
[org.elasticsearch.index.field.data.strings.StringDocFieldData@2a09a0]]
\n[Near : {... \_score \* doc[user] ....}]\n ^\n[Line: 1,
Column: 1]]; nested: ElasticSearchIllegalArgumentException[No field
found for
[org.elasticsearch.index.field.data.strings.StringDocFieldData@2a09a0]];
Now if I want to use \_source.user then it gives correct output. Can
somebody tell me what is the difference in doc['field\_name'] and
\_source.field\_name and when to use it?
Can I use non-numeric values in source.field\_name and use functions on
them like .toString.length()
Regards.

Also what happens if the field is not present? Does Elastic Search
throw any error?

Hi Nachiket
Please keep the conversation on the list.

you will see that it uses "doc['fieldname'].value" and variants.
So for you example above, try:
"\_score + doc['email'].stringValue.length()/10"

I'm not sure if stringValue will take care of the null values or not.
If it doesn't then check if that field has a value before applying the
rest of the calculation.

yes and yes.

Hi.
Thanks for the help.
But I am still getting same error on the last point.
If I use \_souce.field\_name then it gives output correctly but instead
if I use doc['field\_name'] (Even without nesting) then it throws an
error.
nested: ElasticSearchIllegalArgumentException
[No field found for
[org.elasticsearch.index.field.data.strings.StringDocFieldData@1d08960
]
]
I am not getting difference between those. In documentation there is a
point that
"In all scripts that can be used in facets, allow to access the
current doc score using doc.score"
Does this mean there are only some of scripts where I can use
doc['field\_name'] and its variants?
Thanks for the help in advance.
Regards.

Hi.
My script works if I am using \_source.field\_name but doesn't work if I
use doc['field\_name'] (or its variants as stated in documentation).
Can somebody tell me if there is any difference in these two?
If yes how can I use functions like distance() etc using
\_source.field\_name ?
Regards.

Hi. I want to write my own scripts in java.
>
What I can't figure out is how scripts work.
I mean \_source.field\_name works for a field but instead if I use
doc['field\_name'] it throws an error like No field found for
'field\_name'.
Is there any difference between those too on logical level?
If yes how can I use functions like getDistance etc?

Hi.
I was not able to post in my earlier post Errot in script. So I am
starting new discussion.
I want to understand basic difference between doc['field\_name'] ,
\_fields['field\_name'] and \_source.field\_name.
My query works for \_source.field\_name but same query when
doc['field\_name'] is used throws an error named
"ElasticSearchIllegalArgumentException : No field found for ......"
So there must be some difference between those three.
Can somebody help me with this issue?
Regards.

With the gist, suddenly all becomes clear ๐
The ' around the field name are interfering with the ' wrapping your
whole query.
Try this: (embedded ' encoded as \u0027)
curl -XGET '[http://127.0.0.1:9200/twitter/script/\_search?pretty=1](http://127.0.0.1:9200/twitter/script/_search?pretty=1)' -d '

"script" : "1.0 + doc[\u0027user\u0027].value",
"query" : {
"match\_all" : {}
}
}
}
}
'
And regarding your question about \_source vs doc, it is all explained
on the scripting page that i linked you to

Thanks both... I had the same problem
IMHO this \u0027 trick should be mentioned in the docs around [http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-scripting.html](http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/modules-scripting.html)
