| To use Solr as Moodle's search engine you need the PHP Apache Solr extension and a Solr server.
| |
| | |
| == PHP Apache Solr extension ==
| |
| | |
| You need PHP Apache Solr extension installed. Use PECL Solr Extension 1.x for Solr Server 3.x, or use PECL Solr 2.x for Solr Server 4.0+.
| |
| | |
| You can download the official latest versions from [http://pecl.php.net/package/solr](http://pecl.php.net/package/solr)
| |
| | |
| === Linux ===
| |
| | |
| sudo apt-get install libpcre3-dev libxml2-dev libcurl4-openssl-dev
| |
| sudo pecl install solr
| |
| sudo service apache2 restart
| |
| sudo echo `"extension=solr.so" > /etc/php5/apache2/conf.d/solr.ini`
| |
| sudo echo `"extension=solr.so" > /etc/php5/cli/conf.d/solr.ini`
| |
| | |
| === OSX using macports ===
| |
| | |
| sudo port install apache-solr4
| |
| sudo port install php54-solr
| |
| | |
| === Windows ===
| |
| | |
| Install the pecl package as usual. Sorry it has not been tested yet.
| |
| | |
| | |
| == Solr server ==
| |
| | |
| The following snippet (feel free to copy & paste into a .sh script with execution permissions) will download Apache Solr 5.4.1 in the current directory, start the solr server and create an index in it named '''moodle''' to add moodle data to it.
| |
| | |
| | |
| #!/bin/bash
| |
| set -e
| |
| SOLRVERSION=5.4.1
| |
| SOLRNAME=solr-$SOLRVERSION
| |
| SOLRTAR=$SOLRNAME'.tgz'
| |
| CORENAME=moodle
| |
| if [ -d $SOLRNAME ]; then
| |
| echo "Error: Directory $SOLRNAME already exists, remove it before starting the setup again."
| |
| exit 1
| |
| fi
| |
| if [ ! -f $SOLRTAR ]; then
| |
| wget http://apache.mirror.digitalpacific.com.au/lucene/solr/$SOLRVERSION/$SOLRTAR
| |
| fi
| |
| tar -xvzf $SOLRTAR
| |
| cd $SOLRNAME
| |
| bin/solr start
| |
| bin/solr create -c $CORENAME
| |
| # After setting it up and creating the index use:
| |
| # - "/yourdirectory/solrdir/bin/solr start" from CLI to start the server
| |
| # - "/yourdirectory/solrdir/bin/solr stop" from CLI to stop the server.
| |
| | |
| = Setup =
| |
| | |
| # Go to '''Site administration -> Plugins -> Search -> Manage global search'''
| |
| # Enable global search, select '''Solr''' as search engine and tick all search components checkboxes
| |
| # Go to '''Site administration -> Plugins -> Search -> Solr'''
| |
| # Set '''Host name''' to localhost, '''Port''' to 8983 and '''Collection name''' to 'moodle' (the name of the index in Solr)
| |
| # The following script will add the required fields used by Moodle to the Solr index you just created.
| |
| | |
| php search/engine/solr/cli/setup_schema.php
| |
| | |
| | |
| = Indexing =
| |
| | |
| Once global search is enabled a new task will be running through cron, although you can force documents indexing by:
| |
| | |
| # Going to '''Reports -> Search'''
| |
| # Tick '''Recreate index''' and '''Delete''' checkboxes and press '''Save changes'''
| |
| | |
| or
| |
| | |
| * Executing the following task from CLI
| |
| | |
| php admin/tool/task/cli/schedule_task.php --execute="\\core\\task\\search_task"
| |
| | |
| = Querying =
| |
| | |
| # Add '''Global search''' block somewhere
| |
| # Search stuff
| |
