Search

The built in search system is used for:

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

Index Rebuilding

If you want to rebuild the search index (e.g. after updating/restore backup), you have two methods:

Browser

Log in to your HumHub with an administrator account and go to the following section: Administration -> Information -> Database.

On this page click on the button "Rebuild search index". The process can take several minutes.

Console

To start the rebuild job, you need to run following command:

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

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 -maxFileSizeBytes=67108864 --text {fileName} 2>/dev/null',
                                 'except' => ['image/', 'application/x-tar', 'application/zip', ]
                            ],
                         ]
                    ]
                ]
            ],
            
        ],
    ];

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',
            ]
        ]
        // ...
    ];
