Tao 3.1 allows different search implementations. By default it uses a slightly modified version of the Zend Lucene engine, but it can also be connected to Solr.

Installing Solr

Download and install Solr from https://lucene.apache.org/solr/

  • Installation Solr Centos
  • Installation Solr MacOs

Install Solarium library

To add solarium support to Tao you will need to manually add the library to your required packages, this will also install Solarium (http://www.solarium-project.org/)

"require" : {
    "oat-sa/lib-tao-solarium" : "dev-master"

Configure Solr

You have to run and create core based on default tao preset

solr start\ solr create_core -c CORE_NAME -d

Activation script assumes that


If different name was used please make sure to change also [PATH] parameter on configuration step to solr/CORE_NAME

Configure Tao

Modify the configuration to match your Solr server by specifying parameters:

sudo -u www-data php
TAO_ROOT_DIRECTORY\/vendor/oat-sa/lib-tao-solarium/bin/activateSolarium.php TAO_ROOT_DIRECTORY [HOST] [PORT] [PATH]

It should return “Switched to Solr search using Solarium”

Search engine configuration is stored in TAO_ROOT_DIRECTORY/config/tao/search.conf.php
