##Examples

Creating an index

In order to be able to make full text search queries you have to create an index.

Usage:

    use TeamTNT\TNTSearch\TNTSearch;

    $tnt = new TNTSearch;

    $tnt->loadConfig([
        'driver'    => 'mysql',
        'host'      => 'localhost',
        'database'  => 'dbname',
        'username'  => 'user',
        'password'  => 'pass',
        'storage'   => '/var/www/tntsearch/examples/'
    ]);

    $indexer = $tnt->createIndex('name.index');
    $indexer->query('SELECT id, article FROM articles;');
    //$indexer->setLanguage('german');
    $indexer->run();

Important: "storage" settings marks the folder where all of your indexes will be saved so make sure to have permission to write to this folder otherwise you might expect the following exception thrown:

[PDOException] SQLSTATE[HY000] [14] unable to open database file *

Note: Your select statment MUST contain an ID field.

Searching

Searching for a phrase or keyword is trivial

    use TeamTNT\TNTSearch\TNTSearch;

    $tnt = new TNTSearch;

    $tnt->loadConfig($config);
    $tnt->selectIndex("name.index");

    $res = $tnt->search("This is a test search", 12);

    print_r($res); //returns an array of 12 document ids that best match your query

    //to display the results you need an additional query
    //SELECT * FROM articles WHERE id IN $res ORDER BY FIELD(id, $res);
