【ElasticSearch】对于在laravle中搜索的优化

分别对于是category根据商品分类查询，getParams获取查询格式，keywords根据关键词查询，orderby排序，paginate 分页，sale是否上架
  // 添加分页查询
    public function paginate($size, $page)
    {
        $this->params['body']['from'] = ($page - 1) * $size;
        $this->params['body']['size'] = $size;
        return $this;
    }
    // 筛选上架状态的商品
    public function sale()
    {
        $this->params['body']['query']['bool']['filter'][] = ['term' => ['sale' => 1]];
        // ['term' => ['sale' => 1]],
        return $this;
    }
    // 按类目筛选商品
    public function category(GoodsCategory $category)
    {
        if ($category->level != 2) {
            $this->params['body']['query']['bool']['filter'][] = [
                'prefix' => ['category_path' => $category->possess.$category->id.'-'],
            ];
        } else {
            $this->params['body']['query']['bool']['filter'][] = ['term' => ['category_id' => $category->id]];
        }
    }
    // 添加搜索词
    public function keywords($keywords)
    {
        // 如果参数不是数组则转为数组
        $keywords = is_array($keywords) ? $keywords : [$keywords];
        foreach ($keywords as $keyword) {
            $this->params['body']['query']['bool']['must'][] = [
                'multi_match' => [
                    'query'  => $keyword,
                    'fields' => [
                        'title^3',
                        'long_title^2',
                        'category^2', // 类目名称
                        'desc',
                        'skus_attr_name',
                    ],
                ],
            ];
        }
        return $this;
    }
    // 添加排序
    public function orderBy($field, $direction)
    {
        if (!isset($this->params['body']['sort'])) {
            $this->params['body']['sort'] = [];
        }
        $this->params['body']['sort'][] = [$field => $direction];
        return $this;
    }
    // 返回构造好的查询参数
    public function getParams()
    {
        return $this->params;
    }
如上代码
修改控制器：
    $page    = $request->input('page', 1);
        $perPage = 6;
        // 新建查询构造器对象，设置只搜索上架商品，设置分页
        $builder = (new GoodsEsBuilder())->sale()->paginate($perPage, $page);
        if ($request->input('category_id') && $category = GoodsCategory::find($request->input('category_id'))) {
            // 调用查询构造器的类目筛选
            $builder->category($category);
        }
        if ($search = $request->input('search', '')) {
            $keywords = array_filter(explode(' ', $search));
            // 调用查询构造器的关键词筛选
            $builder->keywords($keywords);
        }
       $builder->orderBy('pv', 'desc');
        // 最后通过 getParams() 方法取回构造好的查询参数
        return app('es')->search($builder->getParams());
