I currently have this request:
'query' => 'multi_match' => [ 'query' => $queryString, 'type' => 'bool_prefix', 'fields' => [ 'label^3', 'categories_list', 'tags_list', ], 'operator' => 'and', ] ]
Which does what i want, for example if i type "quick brown fox" i want to match all this words using those 3 fields.
Now what i want is to have an additional field only for boosting the score, lets say it's name is "keyword". So "Cute quick brown fox" would have a higher score but "quick brown fox" would still match.
How can i achieve this ?
