Question on function score script

Elastic Stack Elasticsearch
1

Hi everyone - I am facing an error when executing a function score query
and just wanted to get your comments on the same.

This is the script:
"script_score": {
"script": "doc['boostValue'].value >0 ? ( _score *
doc['boostValue'].value ) : _score"
}

It primarily says that if the boostValue is positive, then multiply _score
by it else use _score as is. The error I get is below:

reason: QueryPhaseExecutionException[[index_type_1][0]: query[function
score (filtered(website:bank
name:bank)->cache(region:US),function=script[doc['boostValue'].value >0 ? (
_score * doc['boostValue'].value ) : _score], params
[null])],from[0],size[5]: Query Failed [Failed to execute main query]];
nested: PropertyAccessException[[Error: could not access: value; in class:
org.elasticsearch.index.fielddata.ScriptDocValues$Empty] [Near : {...
doc['boostValue'].value >0 ? ( ....}] ^ [Line: 1, Column: 1]];

Any thoughts?

-Amit.

Hey,

most likely some document which matched your query does not contain the
field boostValue...

And you can test for it if needed:

doc['boostValue'].isEmpty()

thanks Alex and Binh. I tried with isEmpty() check and it worked fine.
