Hi,

I know something like this was already answered but it's not what I need 🙂

I have two documents that look like this:

{  
"image" : {  
"lists" : [  
{  
"value" : "dior",  
"my\_boost" : "10"  
},  
{  
"value" : "red",  
"my\_boost" : "2"  
}  
]  
}  
}

{  
"image" : {  
"lists" : [  
{  
"value" : "dior",  
"my\_boost" : "2"  
},  
{  
"value" : "red",  
"my\_boost" : "10"  
}  
]  
}

If I search for "red" I will get these two documents.

BUT 🙂

I would like the query to use the my\_boost field to push the score higher  
for the relevant search

This means that I want the second document to be first (because it has a  
my\_boost=10).

I was thinking that custom\_score & script might help me - but I don't know  
how to accomplish it.

Any help will be appreciated.

Noam.

You need to show us your mapping for the fields and also your query.

To my knowledge, the only way to use \_boost values on specific keywords is  
via the \_all field. (I'm not 100% sure but I've tried to make this work for  
a long time and the only success I've had is querying \_all field.)

[Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/mapping/all-field.html). By  
default, all properties are copied over to the \_all field.

Next you must query on your \_all field. The easiest way to do that is to  
omit any field scoping from the query; this will default search the \_all  
field:

curl -XGET  
'localhost:9200/index/\_search?&search\_type=dfs\_query\_then\_fetch&pretty=true'  
-d '{  
"query": {  
"query\_string": {  
"query": "red"  
}  
},  
"sort": [{"\_score": "desc"}],  
"explain": true  
}'

Notice I'm using dfs\_query\_then\_fetch [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/search/search-type.html).  
This will give you more accurate scoring that you will need.

There are other issues you will need to consider like if "red" is indexed  
anywhere else in the document, it means it will affect the term-frequencies  
and your ranking will be affected.

To receive better help, please post a complete curl  
recreation: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/help/)

We have the similar problem.

Here is our scenario:

We have a magazine DB. each magazine has a list of category tags, each tag  
has weight. Number of tags for each magazine is NOT fixed. The magazine doc  
also has name and attachment fileds.

When searching a keyword "sports",

if the keyword occurs in name filed, the document get boosted - we can use  
boost value for name field.  
if the keyword occurs in attachment, no extra boost.  
_if the keyword occurs in the tags, the document get boosted - we want to  
use the tag weight to boost the doc._

One possible solution I can imagine is using script and custom score and  
sort by cscore. However, as a newbie, I could not figure it out.

Appreciate for any help.

Hi Jade,

First of all thanks for the reply.

This is how the mapping should look like:

{  
"image" : {  
"properties" : {  
"lists" : {  
"properties" : {  
"value" : {"type" : "string"},  
"my\_boost" : {"type" : "string"}  
}  
}  
}  
}  
}

The problem (as I can see 🙂 ) from your solution is that it does not use  
the dynamic boost (my\_boost) I store when indexing the document.

Am I missing something?

Noam.

Noam, only \_boost, and boost are valid boost attribute keys. You cannot use  
an arbitrarily named value for boosting. The mapping you've shown is  
actually mapping an object with properties "value" and "my\_boost". You want  
to be mapping a string type with the value of "value" and the internal  
boost of \_boost:

{  
"message" : {  
"\_value": "boosted value",  
"\_boost": 2.0  
}  
}

Reference: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/mapping/core-types.html)  
(under type String)

I have made a control-test example to highlight boosting by individual  
keyword value: [Elasticsearch curl example for ranking by individual token boosts. You can copy this full input and paste it directly into the command-line. Expected results: The result set should be sorted perfectly by the boost value for the skill "ruby". Please note term-frequencies WILL affect scoring and it's only because these documents have the exact same number of skills (1) that term-frequencies are not an issue. · GitHub](https://gist.github.com/plusjade/4988626)

Please verify you can run this and get back the expected results. Any  
further questions should build off this control test so that we are in  
complete alignment.

The \_boost field is only for index-time boosts. Noam is looking for  
something like a "dynamic" boost, where the value used changes depending  
the the result.

IIRC, custom scorers do not work with nested fields, only parent fields.  
You might want to try a nested queries.

Hi Ivan,

You are right - I need a "dynamic" boost... (Jade - thank you any how..).  
Regarding the nested queries - can you give me an example (that uses a  
"dynamic" boost value) which I can learn from?

Thank you all 🙂

Hi Jade,

Thank you so much for your answer. I think I almost catch what I want

One more question: how multiple keyword boost value in a list impacts the  
document?

In my case, we will have a tag LIST. And some tags may contain same  
term/keyword:

Document 1:  
tag1: "sports", \_boost: 2,  
tag2: "winter sports", \_boost: 1.4,  
tag3: "tech": \_boost: 1.1,  
Content: "blah, blah, sports, blah, blan", \_boost: 1.0

Document 2:  
tag1: "sports", \_boost: 2,  
tag2: "blah music", \_boost: 1.5,  
tag3: "ent", \_boost: 1.3  
Content: "blah, blah, music, blah, blah", \_boost: 1.0

When I search keyword "sports" and sort it by \_score, I assume, document 1  
will be returned before document 2. How the \_score gets computed exactly?

Thanks a lot,

Allen

Hi Jade!

Your example ([Elasticsearch curl example for ranking by individual token boosts. You can copy this full input and paste it directly into the command-line. Expected results: The result set should be sorted perfectly by the boost value for the skill "ruby". Please note term-frequencies WILL affect scoring and it's only because these documents have the exact same number of skills (1) that term-frequencies are not an issue. · GitHub](https://gist.github.com/plusjade/4988626)) is close to what  
I'm trying to do, but when I run it i get an error:

$ curl -XPOST localhost:9200/p/profile -d '{  
"skills": [{ "\_value": "ruby", "\_boost": 5 }]  
}'  
{"error":"UnsupportedOperationException[You cannot set an index-time boost:  
norms are omitted for field 'skills']","status":500}

Am I missing something?

did you change the field mappings? index time boosts are stored in the

I just copy the script and paste it in the terminal, have not changed  
anything in it. I get the error on all curl -XPOST localhost:9200/p/profile  
-d '{

"skills": [{ "\_value": "ruby", "\_boost": 5 }]

}' where \_boost != 1. I'm using the latest stable release (0.20.5 -

Tested now in an older version of Elasticsearch (0.19.0 - 2012-03-01) and  
the example works there. Is there some reason why this doesn't work in the  
newer releases?

A custom\_score script is the way to go, but the other complication is  
that you are using an array of objects. In order to consider the  
properties in each object independently, you need to change lists to be  
of type "nested".

I have written a complete example showing how to achieve what you want  
on stackoverflow:
