Hi,
I'm using following custom score script parameter for customizing the
scoring of my documents.
String script = "doc['po'].value";
But it gives me error that:
[Error: could not access: value; in class:
org.elasticsearch.index.fielddata.ScriptDocValues$Empty
My al documents contain this field but why Elasticsearch is not able to
access the value of this field ?
Any idea ?
I have also included that field in my mapping.
"po": {
"type": "double",
"boost": 4.0
}
We can use boost for such a field right ?
Thanks

That means you have some documents in your index that is missing the "po"
field. You should be able to run a query like this to find out:
{
"query": {
"filtered": {
"filter": {
"missing": {
"field": "po"
}
}
}
}
}

I don't have any document for which po field is empty. I have checked my
mongo collections. Also, earlier it was taking value 1 for all the
documents that was the reason why \_score was same for all the documents. Is
there anything wrong in my mapping field which is causing issue ? Please
help me.

I'm shocked what really is happening.
The output of above query shows all my documents are missing that
particular field value.

That's strange. May I ask which version of ES are you using? Thanks.

Can anyone please tell me if this is a bug in Elasticsearch-0.90.3 ?
Elasticsearch is not able to read the value of a field from the doc. How is
it possible ?

Coder, I can duplicate your problem. I am trying to find out if this is a
bug, or it is by design and will get back to you shortly. Thanks.

I think the apostrophe is your problem
It is not
String script = "doc['po'].value";
but
String script = "doc["po"].value";
For implementing best variant of document boost, you should upgrade
Elasticsearch to 1.0.0.RC1 (or 0.90.4+) and use function score query like
this
