如何优化elasticsearch查询

I have been reading through elastic search docs over the last few months and have continued to optimize my query, but I can't seem to get a search query below 500-600ms. Locally with less data I can get responses in ~80-200ms.

To outline what I am trying to accomplish:

I have 12 different models in Laravel that are searchable from a single search bar. As someone types it is searched and returned in a list of results.

Currently, I have this for my search query. Are there any references for how I can improve this? I looked into multi_match, but I was having issues with partial matches and specifying all fields.

$results = $this->elastic->search([
            'index' => config('scout.elasticsearch.index'),
            'type'  => $type ?? implode(',', array_keys($this->permissions, true, true)),
        'body'  => [
            'query' => [
                'bool' => [
                    'must'   => [
                        [
                            'query_string' => [
                                'query' => "$searchQuery*",
                            ],
                        ],
                    ],
                    'filter' => [
                        [

                            ],
                        ],
