Indexer

DRAFT

Cloudrexx provides to create own indexers. Files can be indexed and searched. The index will be updated on upload, rename, delete and move.

Examples

Create a new Indexer

Create a new Indexer Class and extends the \Cx\Core\MediaSource\Model\Entity\Indexer. Overwrite the getText() method. Here you can convert the content of the files into text.

In this example, the Indexer only fetches the data, because it is a text indexer and the data is already in a text format.

<?php

namespace Cx\Modules\TxtIndexer\Model\Entity;

class TxtIndexer extends \Cx\Core\MediaSource\Model\Entity\Indexer
{

    /**
     * Get text from an indexed file
     *
     * @param $mediaSource \Cx\Core\MediaSource\Model\Entity\MediaSource
     * @param $filepath    string path to file
     *
     * @return string
     */
    protected function getText($filepath)
    {
        $data = '';
        try {
            $objFile = new \Cx\Lib\FileSystem\File($filepath);
            $data = $objFile->getData();
        } catch (\Cx\Lib\FileSystem\FileSystemException $e) {
            \DBG::msg($e->getMessage());
        }
        return $data;
    }
}

Register Indexer

Register your indexer in the ComponentController in the postInit method of your module.

public function postInit(\Cx\Core\Core\Controller\Cx $cx) 
{
     // Create new instance of your Indexer 
     $txtindexer = new \Cx\Modules\TxtIndexer\Model\Entity\TxtIndexer();

     // Set all Extensions your Indexer can handle 
     $txtindexer->setExtensions(array('txt'));

     // Register Indexer
     $this->getComponent('MediaSource')->registerIndexer($txtindexer);
}

Get Matches

Create a new MediaSource instance and call the method getFileSystemMatches($searchterm, $path) to get the indexed search results. Then the index search results can be appended to the normal search results.

$mediaType = new MediaSource($name, $humanName, array($directoryPath, $directoryWebPath), $accessIds);
  
$result = new \Cx\Core_Modules\Listing\Model\Entity\DataSet(
    $mediaType->getFileSystemMatches($searchterm, $path)
);

$search->appendResult($result);
