Elasticsearch syntax error with multi fields search - elasticsearch

Question

I watched Elasticsearch Do's, Don'ts and Pro-Tips by Itamar Syn Hershko
https://www.youtube.com/watch?v=c9O5_a50aOQ
I see multiple conditions in several fields in the following image:

I tried to make it in
my Laravel 5.7 app (with the elasticsearch/elasticsearch plugin) as seen in the following code:
$elasticQuery = [
"bool" => [
'must' => [
'multi_match' => [
'query' => $text,
'fields' => ['name^4', 'description']
],
],
"should" => [
'term' => [
"category_id" => 1,
]
]
]
];
but I got the error :
{"error":{"root_cause":[{"type":"parsing_exception","reason":"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]","line":1,"col":130}],"type":"parsing_exception","reason":"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]","line":1,"col":130},"status":400}
But when I use a simple condition:
$elasticQuery = [
'multi_match' => [
'query' => $text,
'fields' => ['name^4', 'description'],
],
];
I got a valid result:
[hits] => Array
(
[total] => 1
[max_score] => 7.4126062
[hits] => Array
(
[0] => Array
(
[_index] => select_vote
[_type] => vote
[_id] => 16
[_score] => 7.4126062
[_source] => Array
(
[id] => 16
[slug] => in-the-film-babe-what-type-of-animal-was-babe
[name] => In the film Babe, what type of animal was Babe?
[description] => Babe is a 1995 A...
[created_at] => 2018-11-10 09:14:15
[category_id] => 2
[category] => Array
(
[name] => Movie&Cartoons
[slug] => movie-cartoons
[created_at] => 2018-11-10 09:14:12
)
)
)
)
)
is this a valid format for multi-request?
MODIFIED BLOCK # 2:
Making some search I found work:
$elasticQuery = [
"bool" => [
'should' => [
[
"multi_match" => [
"query" => $text,
"type" => "cross_fields",
"fields" => [
"name^4",
"description"
]
]
],
[
'match' => [
'category_id' => [
'query' => 1,
]
]
],
[
'match' => [
'category_id' => [
'query' => 3,
]
]
],
]
]
];
when I need to make a search by text fields and the array of category (1 and 3) in the example above it works but looks like it works like an "OR" condition, but I need to make a restriction like "AND" using SQL terminology...
Which way is correct in order to make a restriction as like "AND"?
Thanks!

If you just change should to must it is not going to work because category_id cannot have two values at the same time (unless it's an array, but it's not).
You need to use the following query instead:
$elasticQuery = [
"bool" => [
'must' => [
[
"multi_match" => [
"query" => $text,
"type" => "cross_fields",
"fields" => [
"name^4",
"description"
]
]
],
],
'filter' => [
[
'terms' => [
'category_id' => [ 1, 3 ]
]
]
]
]
];
