FluxSphinx

FluxSphinx is an implementation of the Sphinx Search Engine for the FluxBB forum.

FluxSphinx aims to provide an alternernative for the native FluxBB's search engine and provides a fulltext search for high-volume forums.

Requirements

• PHP 5.3.3 or newer
• Sphinx 2.0 or newer
• FluxBB 1.4.x

Installation

Step 1: Install Sphinx

Install Sphinx on your server (check if a package is avalaible for your distro).

Step 2: Prepare your FluxBB database

Add the FluxSphinx tables in your FluxBB databases, be careful, check the table prefix:

CREATE TABLE IF NOT EXISTS `fluxbb_search_sphinx` (
  `action` varchar(64) NOT NULL DEFAULT '',
  `param` int(11) DEFAULT NULL,
  `created` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
  KEY `search_sphinx_action` (`action`),
  KEY `search_sphinx_created` (`created`)
);
INSERT INTO `fluxbb_search_sphinx` (`action`, `param`) VALUES ('counter_posts', 0);
INSERT INTO `fluxbb_search_sphinx` (`action`, `param`) VALUES ('tmp_counter_posts', 0);

Step 3: Setup Sphinx

• Apply configuration (sphinx/sphinx.conf).
• Creating the index:

/usr/bin/indexer --config /etc/sphinx/sphinx.conf --all --rotate

• Starting the search daemon:

/usr/bin/searchd --config /etc/sphinx/sphinx.conf

OR

/etc/init.d/searchd start

Step 4: Configure Cronjobs

3,18,33,48 * * * * /usr/bin/indexer --quiet --config /etc/sphinx/sphinx.conf fluxbb_search_posts_delta --rotate >/dev/null 2>&1
30 4 * * * /usr/bin/indexer --quiet --config /etc/sphinx/sphinx.conf fluxbb_search_posts_main --rotate >/dev/null 2>&1; /usr/bin/indexer --quiet --config /etc/sphinx/sphinx.conf fluxbb_search_posts_delta --rotate >/dev/null 2>&1

Step 5: Setup FluxBB

• Install SphinxClient from Sphinx API PHP (put on include folder) or from PECL.
• Add Sphinx configuration to your FluxBB's config.php:

// Sphinx
$sphinx_config = array(
    'host' => 'localhost', // Your sphinx server host
    'port' => 3312, // Your sphinx server port
    'idx_main' => 'fluxbb_search_posts_main', // Main search index
    'idx_delta' => 'fluxbb_search_posts_delta', // Delta search index
    'max_query_time' => 5000, // Timeout search queries after 5 seconds.
    'weights' => array( 'message' => 10, 'subject' => 40 ), // Sets the weighting of certain columns
    'use_pecl' => true // Use C client from PECL
);

• Add fluxbb/include/sphinx.php to include folder.
• Add fluxbb/lang to lang folder.
• Replace search.php by fluxbb/search.php.
