在laravel4中实现全文检索

Posted 2021-02-23

In this tutorial I will go over implementing Full-Text search in Laravel 4 .
Those who have used Laravel 3 in the past may remember that there used to be support for FULLTEXT indexes. This functionality has been removed in Laravel 4 but can still easily be implemented.

<?php
 
use IlluminateDatabaseMigrationsMigration;
use IlluminateDatabaseSchemaBlueprint;
 
class CreatePostsTable extends Migration {
 
	/**
	 * Run the migrations.
	 *
	 * @return void
	 */
	public function up()
	{
		Schema::create('posts', function(Blueprint $table) {
			$table->engine = 'MyISAM'; // means you can't use foreign key constraints
			$table->increments('id');
			$table->string('title');
			$table->text('body');
			$table->timestamps();
		});
 
		DB::statement('ALTER TABLE posts ADD FULLTEXT search(title, body)');
	}
 
	/**
	 * Reverse the migrations.
	 *
	 * @return void
	 */
	public function down()
	{
		Schema::table('posts', function($table) {
	    	$table->dropIndex('search');
		});
		Schema::drop('posts');
	}
 
}
