How to run a script_field query?

Elastic Stack Elasticsearch
1

I have following query in a file called query.json

{
"script_fields": {
"correctYear": {
"script": "_source.year – 1800"
}
},
"query": {
"term": {
"title": "crime"
}
}
}

I then execute the query in command-line as below.

curl -XGET 'localhost:9200/library/book/_search?pretty=true' -d @query.json

But I get an error.

SearchPhaseExecutionException: Error: unknown class or illegal statement:
org.elasticsearch.common.mvel2.ParserContext@7a0bd150

The data type of "year" field is long.

Thank you.

Hi Eric,

The minus operator is - and not –. The following script should work:
{
"script_fields": {
"correctYear": {
"script": "_source.year - 1800"
}
}
}

Hi Martijn,

Thanks a lot! This resolved the issue.

I copied the example from a PDF file. That should be the cause for this
character.
