Thank you very much for your reply. I tried using script fields, like
this:
"query":{
"match_all": {}
},
"script_fields":{
"test1":{
"script": "_source.title.length"}
}
}
but my issue now is that I get "PropertyAccessException: Could not access
length". My title field is of type string and I was expecting ElasticSearch
to know about it. I am also using CURL for queries, is there any way to
overcome this error?
Thank you,
Cristina
