composer require islem-kms/searchable
Add the trait to your model and your search rules.
use IslemKms\Searchable\SearchableTrait;
class User extends \Eloquent
{
use SearchableTrait;
/**
* Searchable rules.
*
* @var array
*/
protected $searchable = [
/**
* Columns and their priority in search results.
* Columns with higher values are more important.
* Columns with equal values have equal importance.
*
* @var array
*/
'columns' => [
'users.first_name' => 10,
'users.last_name' => 10,
'users.bio' => 2,
'users.email' => 5,
'posts.title' => 2,
'posts.body' => 1,
],
'joins' => [
'posts' => ['users.id','posts.user_id'],
],
];
public function posts()
{
return $this->hasMany('Post');
}
}Now you can search your model.
// Simple search
$users = User::search($query)->get();
// Search and get relations
// It will not get the relations if you don't do this
$users = User::search($query)
->with('posts')
->get();As easy as laravel default queries
// Search with relations and paginate
$users = User::search($query)
->with('posts')
->paginate(20);Search method is compatible with any eloquent method. You can do things like this:
// Search only active users
$users = User::where('status', 'active')
->search($query)
->paginate(20);The default threshold for accepted relevance is the sum of all attribute relevance divided by 4. To change this value you can pass in a second parameter to search() like so:
// Search with lower relevance threshold
$users = User::where('status', 'active')
->search($query, 0)
->paginate(20);The above, will return all users in order of relevance.
By default, multi-word search terms are split and Searchable searches for each word individually. Relevance plays a role in prioritizing matches that matched on multiple words. If you want to prioritize matches that include the multi-word search (thus, without splitting into words) you can enable full text search by setting the third value to true. Example:
// Prioritize matches containing "John Doe" above matches containing only "John" or "Doe".
$users = User::search("John Doe", null, true)->get();If you explicitly want to search for full text matches only, you can disable multi-word splitting by setting the fourth parameter to true.
// Do not include matches that only matched "John" OR "Doe".
$users = User::search("John Doe", null, true, true)->get();Searchable builds a query that search through your model using Laravel's Eloquent. Here is an example query
use IslemKms\Searchable\SearchableTrait;
class User extends \Eloquent
{
use SearchableTrait;
/**
* Searchable rules.
*
* @var array
*/
protected $searchable = [
'columns' => [
'first_name' => 10,
'last_name' => 10,
'bio' => 2,
'email' => 5,
],
];
}$search = User::search('Sed neque labore', null, true)->get();select `users`.*,
-- If third parameter is set as true, it will check if the column starts with the search
-- if then it adds relevance * 30
-- this ensures that relevant results will be at top
(case when first_name LIKE 'Sed neque labore%' then 300 else 0 end) +
-- For each column you specify makes 3 "ifs" containing
-- each word of the search input and adds relevace to
-- the row
-- The first checks if the column is equal to the word,
-- if then it adds relevance * 15
(case when first_name LIKE 'Sed' || first_name LIKE 'neque' || first_name LIKE 'labore' then 150 else 0 end) +
-- The second checks if the column starts with the word,
-- if then it adds relevance * 5
(case when first_name LIKE 'Sed%' || first_name LIKE 'neque%' || first_name LIKE 'labore%' then 50 else 0 end) +
-- The third checks if the column contains the word,
-- if then it adds relevance * 1
(case when first_name LIKE '%Sed%' || first_name LIKE '%neque%' || first_name LIKE '%labore%' then 10 else 0 end) +
-- Repeats with each column
(case when last_name LIKE 'Sed' || last_name LIKE 'neque' || last_name LIKE 'labore' then 150 else 0 end) +
(case when last_name LIKE 'Sed%' || last_name LIKE 'neque%' || last_name LIKE 'labore%' then 50 else 0 end) +
(case when last_name LIKE '%Sed%' || last_name LIKE '%neque%' || last_name LIKE '%labore%' then 10 else 0 end) +
(case when bio LIKE 'Sed' || bio LIKE 'neque' || bio LIKE 'labore' then 30 else 0 end) +
(case when bio LIKE 'Sed%' || bio LIKE 'neque%' || bio LIKE 'labore%' then 10 else 0 end) +
(case when bio LIKE '%Sed%' || bio LIKE '%neque%' || bio LIKE '%labore%' then 2 else 0 end) +
(case when email LIKE 'Sed' || email LIKE 'neque' || email LIKE 'labore' then 75 else 0 end) +
(case when email LIKE 'Sed%' || email LIKE 'neque%' || email LIKE 'labore%' then 25 else 0 end) +
(case when email LIKE '%Sed%' || email LIKE '%neque%' || email LIKE '%labore%' then 5 else 0 end)
