Installation

You can install the package via composer:

composer require protonemedia/laravel-cross-eloquent-search

Upgrading from v2 to v3

  • The get method has been renamed to search.
  • The addWhen method has been removed in favor of when.
  • By default, the results are sorted by the updated column, which is the updated_at column in most cases. If you don't use timestamps, it will now use the primary key by default.

Upgrading from v1 to v2

  • The startWithWildcard method has been renamed to beginWithWildcard.
  • The default order column is now evaluated by the getUpdatedAtColumn method. Previously it was hard-coded to updated_at. You still can use another column to order by.
  • The allowEmptySearchQuery method and EmptySearchQueryException class have been removed, but you can still get results without searching.

Usage

Start your search query by adding one or more models to search through. Call the add method with the model's class name and the column you want to search through. Then call the search method with the search term, and you'll get a \Illuminate\Database\Eloquent\Collection instance with the results.

The results are sorted in ascending order by the updated column by default. In most cases, this column is updated_at. If you've customized your model's UPDATED_AT constant, or overwritten the getUpdatedAtColumn method, this package will use the customized column. If you don't use timestamps at all, it will use the primary key by default. Of course, you can order by another column as well.

use ProtoneMedia\LaravelCrossEloquentSearch\Search;

$results = Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->search('howto');

If you care about indentation, you can optionally use the new method on the facade:

Search::new()
    ->add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->search('howto');

There's also an when method to apply certain clauses based on another condition:

Search::new()
    ->when($user->isVerified(), fn($search) => $search->add(Post::class, 'title'))
    ->when($user->isAdmin(), fn($search) => $search->add(Video::class, 'title'))
    ->search('howto');

Wildcards

By default, we split up the search term, and each keyword will get a wildcard symbol to do partial matching. Practically this means the search term apple ios will result in apple% and ios%. If you want a wildcard symbol to begin with as well, you can call the beginWithWildcard method. This will result in %apple% and %ios%.

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->beginWithWildcard()
    ->search('os');

Note: in previous versions of this package, this method was called startWithWildcard().

If you want to disable the behaviour where a wildcard is appended to the terms, you should call the endWithWildcard method with false:

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->beginWithWildcard()
    ->endWithWildcard(false)
    ->search('os');

Multi-word search

Multi-word search is supported out of the box. Simply wrap your phrase into double-quotes.

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->search('"macos big sur"');

You can disable the parsing of the search term by calling the dontParseTerm method, which gives you the same results as using double-quotes.

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->dontParseTerm()
    ->search('macos big sur');

Sorting

If you want to sort the results by another column, you can pass that column to the add method as a third parameter. Call the orderByDesc method to sort the results in descending order.

Search::add(Post::class, 'title', 'published_at')
    ->add(Video::class, 'title', 'released_at')
    ->orderByDesc()
    ->search('learn');

You can call the orderByRelevance method to sort the results by the number of occurrences of the search terms. Imagine these two sentences:

  • Apple introduces iPhone 13 and iPhone 13 mini
  • Apple unveils new iPad mini with breakthrough performance in stunning new design

If you search for Apple iPad, the second sentence will come up first, as there are more matches of the search terms.

Search::add(Post::class, 'title')
    ->beginWithWildcard()
    ->orderByRelevance()
    ->search('Apple iPad');

Ordering by relevance is not supported if you're searching through (nested) relationships.

To sort the results by model type, you can use the orderByModel method by giving it your preferred order of the models:

Search::new()
    ->add(Comment::class, ['body'])
    ->add(Post::class, ['title'])
    ->add(Video::class, ['title', 'description'])
    ->orderByModel([
        Post::class, Video::class, Comment::class,
    ])
    ->search('Artisan School');

Pagination

We highly recommend paginating your results. Call the paginate method before the search method, and you'll get an instance of \Illuminate\Contracts\Pagination\LengthAwarePaginator as a result. The paginate method takes three (optional) parameters to customize the paginator. These arguments are the same as Laravel's database paginator.

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')

    ->paginate()
    // or
    ->paginate($perPage = 15, $pageName = 'page', $page = 1)

    ->search('build');

You may also use simple pagination. This will return an instance of \Illuminate\Contracts\Pagination\Paginator, which is not length aware:

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')

    ->simplePaginate()
    // or
    ->simplePaginate($perPage = 15, $pageName = 'page', $page = 1)

    ->search('build');

Constraints and scoped queries

Instead of the class name, you can also pass an instance of the Eloquent query builder to the add method. This allows you to add constraints to each model.

Search::add(Post::published(), 'title')
    ->add(Video::where('views', '>', 2500), 'title')
    ->search('compile');

Multiple columns per model

You can search through multiple columns by passing an array of columns as the second argument.

Search::add(Post::class, ['title', 'body'])
    ->add(Video::class, ['title', 'subtitle'])
    ->search('eloquent');

Search through (nested) relationships

You can search through (nested) relationships by using the dot notation:

Search::add(Post::class, ['comments.body'])
    ->add(Video::class, ['posts.user.biography'])
    ->search('solution');

Full-Text Search

You may use MySQL's Full-Text Search by using the addFullText method. You can search through a single or multiple columns (using full text indexes), and you can specify a set of options, for example, to specify the mode. You can even mix regular and full-text searches in one query:

Search::new()
    ->add(Post::class, 'title')
    ->addFullText(Video::class, 'title', ['mode' => 'boolean'])
    ->addFullText(Blog::class, ['title', 'subtitle', 'body'], ['mode' => 'boolean'])
    ->search('framework -css');

If you want to search through relationships, you need to pass in an array where the array key contains the relation, while the value is an array of columns:

Search::new()
    ->addFullText(Page::class, [
        'posts' => ['title', 'body'],
        'sections' => ['title', 'subtitle', 'body'],
    ])
    ->search('framework -css');

Sounds like

MySQL has a soundex algorithm built-in so you can search for terms that sound almost the same. You can use this feature by calling the soundsLike method:

Search::new()
    ->add(Post::class, 'framework')
    ->add(Video::class, 'framework')
    ->soundsLike()
    ->search('larafel');

Eager load relationships

Not much to explain here, but this is supported as well :)

Search::add(Post::with('comments'), 'title')
    ->add(Video::with('likes'), 'title')
    ->search('guitar');

Getting results without searching

You call the search method without a term or with an empty term. In this case, you can discard the second argument of the add method. With the orderBy method, you can set the column to sort by (previously the third argument):

Search::add(Post::class)
    ->orderBy('published_at')
    ->add(Video::class)
    ->orderBy('released_at')
    ->search();

Counting records

You can count the number of results with the count method:

Search::add(Post::published(), 'title')
    ->add(Video::where('views', '>', 2500), 'title')
    ->count('compile');

Model Identifier

You can use the includeModelType to add the model type to the search result.

Search::add(Post::class, 'title')
    ->add(Video::class, 'title')
    ->includeModelType()
    ->paginate()
    ->search('foo');

// Example result with model identifier.
{
    "current_page": 1,
    "data": [
        {
            "id": 1,
            "video_id": null,
            "title": "foo",
            "published_at": null,
            "created_at": "2021-12-03T09:39:10.000000Z",
            "updated_at": "2021-12-03T09:39:10.000000Z",
            "type": "Post",
        },
        {
            "id": 1,
            "title": "foo",
            "subtitle": null,
            "published_at": null,
            "created_at": "2021-12-03T09:39:10.000000Z",
            "updated_at": "2021-12-03T09:39:10.000000Z",
            "type": "Video",
        },
    ],
    ...
}

By default, it uses the type key, but you can customize this by passing the key to the method.

You can also customize the type value by adding a public method searchType() to your model to override the default class base name.

class Video extends Model
{
    public function searchType()
    {
        return 'awesome_video';
    }
}

// Example result with searchType() method.
{
    "current_page": 1,
    "data": [
        {
            "id": 1,
            "video_id": null,
            "title": "foo",
            "published_at": null,
            "created_at": "2021-12-03T09:39:10.000000Z",
            "updated_at": "2021-12-03T09:39:10.000000Z",
            "type": "awesome_video",
        }
    ],
    ...

Standalone parser

You can use the parser with the parseTerms method:

$terms = Search::parseTerms('drums guitar');

You can also pass in a callback as a second argument to loop through each term:

Search::parseTerms('drums guitar', function($term, $key) {
    //
});
