Best way to search the address equivalent

[armel.conrad]

Hi everyone,

I'm using Elasticsearch PHP API to index an address database with multiple fields. And I use it for an autocomplete search. I base it on a fa field with this as the value "1 AVE Avenue NE Northeast Northeast AIRDRIE AB Alberta T4B0R5 T4B 0R5"

I see providing the mapping and search codes. I want to know if there is a better way to do this.

Thank you for your help.

mapping code

$params = [
            'index' => 'canada_posts',
            'body' => [
                'mappings' => [
                    '_source' => [
                        'enabled' => true
                    ],
                    'properties' => [
                        'fa' => ['type' => 'text'],
                        'sn' => ['type' => 'text'],
                        'sdc' => ['type' => 'text', 'index' => false],
                        'stc' => ['type' => 'text', 'index' => false],
                        'mn' => ['type' => 'text', 'fielddata' => True],
                        'zip' => ['type' => 'keyword'],
                        'pc' => ['type' => 'text', 'fielddata' => True],
                        'sansfc' => ['type' => 'text', 'index' => false],
                        'sanstc' => ['type' => 'text', 'index' => false],
                        'safn' => ['type' => 'integer'],
                        'satn' => ['type' => 'integer'],
                        'sasc' => ['type' => 'integer', 'index' => false],
                        'prov' => ['type' => 'long']
                    ]
