MeiliSearch 索引创建

以PHP代码为例

1、引入 PHP SDK

composer require meilisearch/meilisearch-php http-interop/http-factory-guzzle

2、创建索引

<?php

use Meilisearch\Client;

$client = new Client('http://localhost:7700', 'masterKey');

$client->createIndex('movies', ['primaryKey' => 'id']);

3、导入文档

<?php

$client->index('movies')->addDocuments([
  [
    'id' => 287947,
    'title' => 'Shazam',
    'poster' => 'https://image.tmdb.org/t/p/w1280/xnopI5Xtky18MPhK40cZAGAOVeV.jpg',
    'overview' => 'A boy is given the ability to become an adult superhero in times of need with a single magic word.',
    'release_date' => '2019-03-23'
  ]
]);

4、搜索

<?php

$client->index('movies')->search('american ninja', [
    'hitsPerPage' => 20, # 每页数据量
    'page' => 1, # 页码
    'matchingStrategy' => 'all', # 匹配策略 last, all, or frequency
    'attributesToSearchOn' => ['title', 'overview']  # 限制只将这两个字段作为搜索字段
]);

6、索引重建方法

索引创建后，因为一些后台操作可能导致索引未及时更新，可以采用定时重建索引的方式使索引保持最新的状态

利用交换索引的方式实现以上功能

<?php

use Meilisearch\Client;

# 检查索引是否存在，若不存在创建之；若存在创建新的索引，数据导入后执行交换索引操作，再删除新的索引

$client = new Client('http://localhost:7700', 'masterKey');

$indexName = 'movies';

try {
    $indexInfo = $client->index($indexName)->fetchRawInfo();
} catch (\Exception) {
    $indexInfo = null;
}
if (!empty($indexInfo)) {
    $needSwap = true;
    $indexName = 'movies_new';
}
$client->createIndex($indexName, ['primaryKey' => 'id']);
# 数据导入操作
Movies::query()->where(['status' => 1])
    ->select(['id', 'name', 'desc'])
    ->chunkById(100, function ($musics) use ($client, $indexName) {
        $musics = $musics->toArray();
        $client->index($indexName)->addDocuments($musics);
    });

if ($needSwap) {
    # 交换索引
    $client->swapIndexes([['movies', $indexName]]);
    # 删除刚才新建的索引
    $client->deleteIndex($indexName);
}
