Slide 1: Solr Search and Facets Implementation in Drupal8	Welcome to the spoken tutorial on Solr Search and Facets Implementation.
Slide 2:Learning Objectives Introduction to Solr search Salient features of Solr search Installation of Solr search Creation of Facets	In this tutorial, we will learn about- Introduction to Solr search Salient features of Solr search Installation of Solr search and Creation of Facets
Slide 3: System requirement To record this tutorial, I am using Ubuntu Linux 16.04 OS Drupal 8 Firefox web browser	To record this tutorial, I am using Ubuntu Linux 16.04 Drupal 8 and Firefox web browser You can use any web browser as per your choice.
Slide 4: Pre-requisites You should have basic knowledge of Drupal If not, for relevant Drupal tutorials please visit http://spoken-tutorial.org A working Internet connection	To practise this tutorial, you should have basic knowledge of Drupal. If not, for relevant Drupal tutorials, please visit the link shown. You should also have a working Internet connection.
Slide 5: API Application Programming Interface Set of rules to interact to each other For more details, see the “Additional Material” link	First let us learn what is an API. API stands for Application Programming Interface. It has a set of rules that software programs can follow to interact with each other. More information on API is given in the Additional Material link of this tutorial.
Slide 6: What is Solr Open source search platform used to build Search Application Create custom search engine	What is Solr Search API? Solr is an open source search platform used to build a Search Application. It enables us to create custom search engines that index databases, files and websites.
Slide 7: Solr Search API The default search does database search It leads to slower process and extra load on MySQL Solr provides a different server for searching It will speed up the search operation.	Why do we need Solr Search API? The default search that comes with Drupal does database search. It leads to slower process and extra load on MySQL. But Solr provides a different server for searching. It will speed up the search operation.
Slide 8: Salient Features of Solr Scalable Full text search capabilities Flexible and extensible Friendly user interface Fault tolerance	Some of the features of Solr are listed here. It is scalable. It has full text search capabilities. It is flexible and extensible. It has a friendly user interface. It has fault tolerance. <<PAUSE>>
Slide 9: What is Solr core?	Next we will learn about Solr core. Solr core is used to perform operations like indexing and analyzing It is a single index and associated configuration files We can index data with different structures A Solr server may contain one or multiple cores Multiple cores are used when we need multiple versions, languages, or configurations
	In this example there is one core each for Articles and Weblogs in a single Solr Server Instance.
Show text Solr implementation process Show text Bitnami Drupal Stack	Next let us learn the Solr implementation process step by step. The following steps are applicable to Bitnami Drupal Stack. But most of the steps are applicable to any other Drupal installation, as well.
Show text Step No. 1 Type sudo apt-get update && apt-get upgrade -y Highlight root	Step No. 1 Open your terminal and run the following commands to update and upgrade the machine. Note that you should run this command as a root user.
Show text Step No. 2 Show text JRE or JDK	Step No. 2 Since Solr is based on Java, we need to have JRE or JDK installed in our system.
Type sudo apt-get install python-software-properties	For that, first we need to install python software properties. So run the following command.
Type sudo add-apt-repository ppa:webupd8team/java	Next we will run this command for setting up the Java Runtime Environment.
Type sudo add-apt update	Then to update the system with the unsupported packages, type sudo space add hyphen apt space update Press Enter.
Type sudo apt install oracle-java8-installer	Finally run the following command to install the latest version of oracle Java8.
Type java -version	Now we can check the installed Java version by typing java space hyphen version. Press Enter.
Type sudo apt install oracle-java8-set-default	Next we have to set-up the default Java environment variable. So, run the following command. <<PAUSE>>
Show text Step No. 3	Step No. 3 Next we will learn to install Solr in our local machine.
Type cd /tmp	First we have to change the directory to /tmp.
Type wget http://www-us.apache.org/dist/lucene/Solr/6.6.2/solr-6.6.2.tgz Show text www-us.apache.org/dist/lucene/solr	Now we will download the Solr version 6.6.2 from their web page. Type the following command. Note that you can download any latest version from their website.
Type tar xzf solr-6.6.2.tgz solr-6.6.2/bin/install_solr_service.sh --strip-components=2	Next we will extract the downloaded tar file using the following command.
Type sudo ./install_Solr_service.sh solr-6.6.2.tgz	Now we should install Solr as a service in our system. So type the following command.
Type service Solr status Highlight the status	Then we will check the status of Solr by typing service space Solr space status Press Enter. We can see that the service Solr is installed in our system and activated as well. <<PAUSE>>
Show text Step No. 4 Type sudo su - solr -c "/opt/solr/bin/solr create -c testcollection -n data_driven_schema_configs" Highlight testcollection	Step No. 4 We will now create a new solr core in Solr to index our Drupal content. Type the following command carefully. Here I have named the newly created core as testcollection.
Type in the URL bar - http://localhost:8983/Solr/	By default solr application listens on TCP port 8983. We can access the Solr admin user interface through the port 8983. In the URL bar, type http://localhost:8983/Solr/
Click Core Selector field	In the Core Selector field, we can see the list of all the available core.
Click the core testcollection	Clicking on any particular core, will give us the associated details. That is all about Solr installation in our local system. <<PAUSE>>
Show text Step No. 5 Show text mbstring extension of PHP & Composer Show text Additional Material	Step No. 5 Next we will implement the Solr search API in Drupal8. For this, mbstring extension of PHP and composer should be installed in our machine. The steps to install the above software are given in the Additional Material link of this tutorial.
Type cd /home/spoken/drupal-8.4.4-0/apps/drupal/htdocs	Once the required installation is done, change the directory to /home/spoken/drupal-8.4.4-0/apps/drupal/htdocs.
Type composer config repositories.drupal composer https://packagist.org	After this, we need to install solarium library in Drupal8. Solarium is a Solr client library for PHP. Execute the following command to install it.
Type composer require “drupal/search_API_solr”	Next we will install search API Solr module to Drupal8 via composer. Type the following command.
Type composer require “drupal/facets:^1.0”	We will also download Facets module to Drupal8 to be used later on. Type the following command. At this point, we have downloaded all the required modules. <<PAUSE>>

Click Search Click Uninstall button	Put a check mark on the Search module and click on the Uninstall button at the bottom. You can see that the default Search module is disabled now.
Show text Step No. 6 Switch to terminal Type cp /home/spoken/drupal-8.4.4-0/apps/drupal/htdocs/modules/contrib/search_api_solr/solr-conf/6.x/* /var/solr/data/testcollection/conf Highlight source and destination	Step No. 6 Next we have to allow our Drupal to communicate with Solr. For that, switch back to terminal and run the following command carefully. This will copy the configuration files from modules folder of Drupal8 to the core of Solr.
Type sudo service solr restart	After copying the configuration files, to restart the Solr service, typing sudo space service space solr space restart Press Enter. <<PAUSE>>
