README

Welcome home ! Let me introduce you this package. In fact, this package handles two importants things :

grammar files (MySQL and PostgreSQL) ;
a simple trait ;

ScoreSearch allows you to search thought any of entity that implement the provided trait a new way based on scoring to fetch the more relevant rows. At now, I just tested the package over PostgreSQL. Maybe others database engines will be implemented if someone need them.

Installation

The most basic installation is needed.

composer require 'studio-net/laravel-scoresearch @dev'

Usage

Add the provided trait into the wanted Eloquent model and provides a simple searchable protected variable to list the weight of each element. If a column is not specified, the default weight will be 1.

# app/User.php

namespace App;

use Illuminate\Database\Eloquent\Model;
use StudioNet\ScoreSearch\Searchable;

/**
 * User
 *
 * @see Model
 */
class User extends Model {
	use Searchable;

	/** @var array $searchable */
	protected $searchable = [
		'columns' => [
			'username' => 10,
			'age'      => 5,
			'email'    => 15,
		]
	];
}

Now, you can simply return a search using the search scope, passing as first argument an array of comparaisons to use.

$users = User::search([
		'username' => ['or' => ['cyril', 'studio-net']],
		'email'    => ['or' => ['%@studio-net.fr', '%@studio-net.com'], '%boss'],
		'age'      => '(gt) 20',
	])

	->where('active', true)
	->get();

select * from (
	select users.*, (
		(case when (((username = 'cyril') OR (username = 'studio-net'))) then 10 else 0 end) +
		(case when (((email ilike '%@studio-net.fr') OR (email ilike '%@studio-net.com')) AND (email ilike '%boss')) then 15 else 0 end) +
		(case when (age > 20) then 5 then 0 end)
	) as score from users
) as users where score >= ? and active is true order by score desc

Specification

In order to use operator, you can refer to example below. Otherwise, this is the default syntax to use : (operator) text, excepting for % and = that doesn't need to handle an operator case, just the string within like cyril will produce = cyril and cyril% will produce ilike 'cyril%'.

Relationship

You can specify in your $searchable variable instance a joins array that can handle table names. You can specify the on by setting a subset.

	protected $searchable = [
		'joins'   => ['posts'],
		'joins'   => ['posts' => ['posts.id', 'users.id']],

		'columns' => [
			'posts.title' => 5,
			'user.login'  => 10
		]
	];

	// Fetch users with related posts
	User::search(['user.login' => 'cyril', 'posts.title' => '%toto%'])->with('posts')->get();

Eloquent

You can use every method that Eloquent provides. As this package use a subquery, you can easily make queries like :

User::where('role', 'admin')
	->search(['email' => '%@studio-net.fr'])
	->with('posts')
	->paginate(20);
