Mysql 全文搜索 Laravel 可翻译？

Question

到目前为止，我一直使用这样的全文搜索：

public function posts($search)
{
    $searchString = $this->prepareString($search);
    $posts = Post::select('*')->selectRaw('MATCH(name) AGAINST(? IN NATURAL LANGUAGE MODE) AS relevance', [$searchString])->whereRaw('MATCH(name) AGAINST(? IN NATURAL LANGUAGE MODE)', [$searchString])->orderBy('relevance', 'desc')->get();

    return $posts;
}

这很好用，但是现在我正在使用这个包 Laravel Translatable。 name 字段不是 Post 的一部分，但它是 PostTranslation 的一部分。我如何使用上述查询，但用于翻译？这是我的迁移：

Schema::create('posts', function (Blueprint $table) {
            $table->increments('id');
            $table->timestamps();
        });

Schema::create('post_translations', function (Blueprint $table) {
            $table->increments('id');

            $table->string('name');
            $table->text('body');

            $table->char('locale', 2)->index();

            $table->integer('post_id')->unsigned();
            $table->foreign('post_id')->references('id')->on('posts')->onDelete('cascade');

            $table->unique(['id', 'locale']);
        });

Answer 1

你可以使用 DB Facade 这样的东西

public function posts($search)
{
    $searchString = $this->prepareString($search);
    $posts = DB::table('post_translations')->select('*')->selectRaw('MATCH(name) AGAINST(? IN NATURAL LANGUAGE MODE) AS relevance', [$searchString])->whereRaw('MATCH(name) AGAINST(? IN NATURAL LANGUAGE MODE)', [$searchString])->orderBy('relevance', 'desc')->get();

    return $posts;
}

Answer 2

Laravel 似乎不支持使用 table 蓝图在迁移中指定 FULLTEXT 索引。但是，您可以使用原始查询手动添加它们：

Schema::create('post_translations', function (Blueprint $table) {
    $table->increments('id');

    $table->string('name');
    $table->text('body');

    $table->char('locale', 2)->index();

    $table->integer('post_id')->unsigned();
    $table->foreign('post_id')->references('id')->on('posts')->onDelete('cascade');

    $table->unique(['id', 'locale']);
});
DB::statement('ALTER TABLE post_translations ADD FULLTEXT idx(name)');

然后您可以照常使用全文搜索：

$posts = PostTranslation::select('*')
    ->selectRaw(
      'MATCH(name) AGAINST(? IN NATURAL LANGUAGE MODE) AS relevance', 
      [$searchString]
    )->orderBy('relevance', 'desc')->get();
