Plugin / Solr Search for WordPress

Installation

The Solr Power plugin can be installed just like you’d install any other WordPress plugin.

Because Solr Power is intended to be a bridge between WordPress and the Apache Solr search engine, you’ll need access to a functioning Solr 3.6 instance for the plugin to work as expected. This plugin does not support other versions of Solr. The plugin also requires PHP 7.1 or higher.

If you’re using the Solr Power plugin on Pantheon, setting up Apache Solr is as easy as enabling the Apache Solr add-on in your Pantheon dashboard. Once you’ve done so:

1. Configure which post types, taxonomies and custom fields to index by going to the Indexing tab of the Solr Power settings page.
2. Index your existing content by going to the plugin options screen and selecting the applicable Actions:
   • • Index Searchable Post Types
3. Search on!
4. See the examples/templates directories for more rich implementation guidelines.

If you’re using the Solr Power plugin elsewhere, you’ll need to install and configure Apache Solr. On a Linux environment, this involves four steps:

1. Install the Java Runtime Environment.
2. Run ./bin/install-solr.sh to install and run Apache Solr on port 8983.
3. Configuring Solr Power to use this particular Solr instance by setting the PANTHEON_INDEX_HOST and PANTHEON_INDEX_PORT environment variables.
4. Copying schema.xml to the Solr configuration directory (a path similar to solr/conf/schema.xml).

Alternatively, there are a couple of community-maintained Docker containers you may be able to use: kalabox/pantheon-solr, kshaner/solr.

In a local development environment, you can point Solr Power to a custom Solr instance by creating a MU plugin with:

`

<?php
/**
* Define Solr host IP, port, scheme and path
* Update these as necessary if your configuration differs
*/
putenv( ‘PANTHEON_INDEX_HOST=192.168.50.4’ );
putenv( ‘PANTHEON_INDEX_PORT=8983’ );
add_filter( ‘solr_scheme’, function(){ return ‘http’; });
define( ‘SOLR_PATH’, ‘/solr/wordpress/’ );
`
