Laravel全文搜索 [英] Laravel full text search

问题描述

我正在尝试对数据库实施全文搜索查询.这是我的客户发送给我的规范:

I'm trying to implement a full text search query to the database. This is in the specification that my client sent me:

"The free text search limits the result of the data table to records with a matching first
name, last name, country, city, state, or zip code. If several words are input,
each word must match one of the columns for a record to be visible."

我在控制器中做了一些非常难看的意大利面条代码，以尝试是否有效:

I made some very ugly spaghetti code in my controller to try if it works:

public function search($searchTerms){
        $searchTerms = explode(' ', $searchTerms);
        $results = array();
        foreach ($searchTerms as $searchTerm) {
            if (!People::where('firstname', 'LIKE', '%'.$searchTerm.'%')->get()->isEmpty()) {
                array_push($results, People::where('firstname', 'LIKE', '%'.$searchTerm.'%')->get());
            }
            else if (!People::where('lastname', 'LIKE', '%'.$searchTerm.'%')->get()->isEmpty()) {
                array_push($results, People::where('lastname', 'LIKE', '%'.$searchTerm.'%')->get());
            }
        }
        return $results;
    }

这是我对此函数的调用:

And this is my call to this function:

$data->people = $this->search(Input::get('search'));

问题是，如果没有搜索输入，我将使用它来获取所有数据:

The problem is that if there is no search input, I use this to get all data:

$data->people = People::orderBy($order)->paginate(10);

通过将搜索结果作为数组获取，我在视图中得到以下错误:

And by getting the search results as an array, I get the following error in my views:

Undefined property: Illuminate\Database\Eloquent\Collection::$firstname (View: /home/projects/pplproject/app/views/index.blade.php) 

该如何以 Laravel方式实现?

推荐答案

基本上，这里的目标应该是在一个查询中全部运行.去吧:

Basically, the goal here should be to run this all in one query. Here goes:

$searchTerms = explode(' ', $searchTerms);
$query = People::query();

foreach($searchTerms as $searchTerm){
    $query->where(function($q) use ($searchTerm){
        $q->where('firstname', 'like', '%'.$searchTerm.'%')
        ->orWhere('lastname', 'like', '%'.$searchTerm.'%')
        ->orWhere('country', 'like', '%'.$searchTerm.'%')
        // and so on
    });
}

$results = $query->get();

对于相关模型，您可以尝试执行以下操作:

For related models you can try something like this:

foreach($searchTerms as $searchTerm){
    $query->where(function($q) use ($searchTerm){
        $q->where('firstname', 'like', '%'.$searchTerm.'%')
        ->orWhereHas('relationName', function($relation) use ($searchTerm){
            $relation->where('relation_attribute', 'like', '%'.$searchTerm.'%');
        });
    });
}
