Installation

Before installing Search Lucene API, make sure you review the Installing contributed modules tutorial. Search Lucene API is installed like any standard Drupal module with one exception; The required Zend Framework components must be downloaded separately. Due to Drupal's strict licensing policy regarding non-GPL code, the ZF components cannot be bundled with the module on Drupal.org. However, no action other than retrieving the files from the Search Lucene API Library project on SourceForge.net and moving the extracted directory to the correct location is required. Complete installation instructions are as follows:

1. Download the Search Lucene API module from the project page. Make sure the version of the module matches your version of Drupal. For example, the 6.x-2.0 version is suitable for Drupal 6 but will not work for Drupal 5.
2. Extract the files. Modules downloaded from drupal.org are compressed to reduce their size and must be extracted before they can be used on your website. The result of this action will be a 'luceneapi' directory containing the module's source code files. For a tutorial on how to extract compressed files, please refer to the “Installing contributed modules” tutorial.
3. Download the required Zend Framework components from the Search Lucene API Library project on SourceForge.net. Match the release of the ZF components to the version of the module downloaded in step 1. For example, the 6.x-2.0 version of Search Lucene API requires the 6.x-2.0 version of the ZF components. If there is no exact match, download the latest available version of the ZF components up to, but not exceeding, the the minor version of the downloaded module. The Status report page in the administration section of your website will alert you if the ZF components require updating.
• Project page: http://sourceforge.net/projects/luceneapi
4. Extract the ZF components files as done in step 2. The result of this action will be a directory named 'lib'.
5. Move the 'lib' directory into the 'luceneapi' directory. From this point forward, it is assumed the 'luceneapi/lib' directory contains the requires ZF components.
6. Upload the 'luceneapi' directory to your Drupal installation. In most cases, the module will reside in 'sites/all/modules'. Please refer to the "Installing contributed modules" tutorial for more information.
7. Enable the modules. Navigate to Administer > Site building > Modules and check the 'Enabled' box next to Search Lucene API and Search Lucene Content. Scroll down to the bottom of the page and click the 'Save Configuration' button.
8. As of Search Lucene API 6.x-2.0-beta3, the Search Lucene Content index can be populated via a batch process by visiting Administer > Site configuration > Search Lucene Content and clicking on the Index statistics tab. Once there, select the Rebuild index after operation checkbox and click the Re-index button. It is critical that cron is configured otherwise changes to the content will not be reflected in the search index. For more information on configuring cron, please refer to the Configuring cron jobs tutorial. It is worth noting that Search Lucene API is compatible with projects such as Super Cron.
