You could use a boosting query
<http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-boosting-query.html>,
or you could use a multi-match query
<http://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-multi-match-query.html>
and
add a boost directly to the name and id fields. Something like:
{
"multi_match": {
"fields": [
"name^2",
"id^2",
"_all"
],
"query": keyword,
"type": "best_fields"
}
}
That tells Elasticsearch to search all fields, but to additionally search
name and id and double their score if they match (that's the "^2" part).
the "best_fields" type will use the best score from the name, id, and _all
searches. You might want most_fields to rank records that contain your
query terms in name *and* id *and* other fields even higher. Note that my
snippet is using the Query DSL. The syntax for the client you're using will
probably be slightly different but that's the general idea.
Also note that I've been using Elasticsearch less than a year though so
there may be better approaches, but that's where I'd start.
