Match, multi_match and boosting fields

Elastic Stack Elasticsearch
#1

Hi all,

I've seen on this message
https://groups.google.com/d/msg/elasticsearch/HESISfuupyc/wQJGiPJeZOcJ that
multi_match field parameter support to boost field with a syntax like
QueryString : field^2

It's pretty useful, but the match query does not support this notation.

Following doesn't work :

{
"match" : {
"message^2" : "this is a test"
}
}

The easiest solution is to use multi_match query even if I know that I search only one field ... is there any drawback with this solution ?

Regards.

All queries support the boost parameter in the query dsl to boost
individual queries.
