Search

Search allows you to easily add an intelligent search engine to your website or web application. It can be configured to search any database table.

Installation

You can install this package with Composer.

composer require rapidwebltd/search

Usage

Using Search is easy. Take a look at the following example.

use \RapidWeb\Search\Search;

// Setup your database connection. 
// If you already have a connection setup, you can skip this step.
$pdo = new PDO('mysql:dbname=database_name;host=127.0.0.1', 'username', 'password');

// Create a new Search object
$search = new Search;

// Configure the Search object
$search->setDatabaseConnection($pdo)
       ->setTable('products')
       ->setPrimaryKey('product_groupid')
       ->setFieldsToSearch(['product_name', 'product_description', 'product_seokeywords'])
       ->setConditions(['product_live' => 1]);

// Perform a search for 'test product', limited to top 10 results
$results = $search->query('test product', 10);

// Output results
var_dump($results);

The results are returned as a SearchResults object, as shown below, containing an array of SearchResult objects. This SearchResults object also contains various statistics such as the highest, lowest and average relevances, and the time taken to perform the search.

Each SearchResult object in the array provides the primary key id and its relevance. The relevance is simply a number that is higher on more relevant results. The array is sorted by relevance descending.

object(RapidWeb\Search\SearchResults)#731 (5) {
  ["results"]=>
  array(10) {
    [0]=>
    object(RapidWeb\Search\SearchResult)#588 (2) {
      ["id"]=>
      int(80)
      ["relevance"]=>
      float(637.80198499153)
    }
    /** ... snipped ... */
    [9]=>
    object(RapidWeb\Search\SearchResult)#597 (2) {
      ["id"]=>
      int(18469)
      ["relevance"]=>
      float(121.65783596237)
    }
  }
  ["highestRelevance"]=>
  float(637.80198499153)
  ["lowestRelevance"]=>
  float(121.65783596237)
  ["averageRelevance"]=>
  float(336.74613218217)
  ["time"]=>
  float(0.33661985397339)
}

Caching Source Data

To speed up searching, you can cache the source data using any PSR-6 compliant cache pool. An example of this is shown below.

// Create cache pool
$filesystemAdapter = new Local(storage_path().'/search-cache/');
$filesystem = new Filesystem($filesystemAdapter);
$cacheItemPool = new FilesystemCachePool($filesystem);

// Set cache expiry time
$cacheExpiryInSeconds = 300;

// Create a new Search object
$search = new Search;

// Configure the Search object
$search->setDatabaseConnection($pdo)
       ->setTable('products')
       ->setPrimaryKey('product_groupid')
       ->setFieldsToSearch(['product_name'])
       ->setCache($cacheItemPool, $cacheExpiryInSeconds); // Setup cache
