Search

The built in search system is used for:

• Directory
• People/Space Search
• Content Search
• User/Space Picker Widgets

Index Rebuilding

If you need to rebuild the search index (e.g. after updating) you need to run following command:

cd /path/to/humhub/protected
php yii search/rebuild

or by means of grunt:

grunt build-search

File Content Indexing

In order to allow also indexing of file contents (e.g. PDF, Word or PowerPoint document) you can specify file parsers in your configuration.

We recommend Apache Tika as parser software which supports thousand of different file types.

Example configuration:

    return [
        // ...
        
        'modules' => [
            // ...
            
            'file' => [
                'converterOptions' => [
                    'humhub\modules\file\converter\TextConverter' => [
                        'converter' => [
                            [
                                'cmd' => '/usr/bin/pdftotext -q -enc UTF-8 {fileName} {outputFileName}',
                                'only' => ['pdf']
                            ],
                            [
                                 'cmd' => '/usr/bin/java -jar /srv/www/var/lib/tika-app-1.18.jar --text {fileName} 2>/dev/null',
                                 'except' => ['image/']
                            ],
                         ]
                    ]
                ]
            ],
            
        ],
    ];

Zend Lucence Engine

By default, HumHub is using a Lucence Index (Zend Lucence) to store search data.

Default database folder: /protected/runtime/searchdb/

You can modify the default search directory in the configuration:

    return [
        // ...
        'params' => [
            'search' => [
                'zendLucenceDataDir' => '/some/other/path',
            ]
        ]
        // ...
    ];
