Apache Solr Multilingual Search: Core-per-language Example

This is an article related to the Apache Solr Multilingual Search: Core-per-language. Generally, Apache Solr is used for search and browsing categories and facets.

1. Introduction

Apache Solr is an open-source software java search engine. It is scalable and can process a high volume of data. It is used to index the content and search a huge amount of content. It is a popular search engine. It is used as a document based NOSQL data source. It can be also used as a key value store. Solr has JSON, XML, and HTTP REST API.

2.1 Prerequisites

Java 7 or 8 is required on the Linux, windows, or Mac operating system. Apache Solr 4.7.0 is required for this example.

2.2 Download

You can download Java 8 can be downloaded from the Oracle website. Apache Solr’s latest releases are available from the Apache Solr website.

2.3 Setup

You can set the environment variables for JAVA_HOME and PATH. They can be set as shown below:

Setup
JAVA_HOME="/desktop/jdk1.8.0_73"
export JAVA_HOME
PATH=$JAVA_HOME/bin:$PATH
export PATH

2.4 How to download and install Apache Solr

Apache Solr’s latest releases are available from the Apache Solr website. After downloading the zip file can be extracted to a folder.

To start the Apache Solr, you can use the command below:

Solr start command
bin/solr start

The output of the above command is shown below:

Solr start command output
apples-MacBook-Air:solr-8.8.2 bhagvan.kommadi$ bin/solr start
*** [WARN] *** Your open file limit is currently 2560.  
 It should be set to 65000 to avoid operational disruption. 
 If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in your profile or solr.in.sh
*** [WARN] ***  Your Max Processes Limit is currently 1392. 
 It should be set to 65000 to avoid operational disruption. 
 If you no longer wish to see this warning, set SOLR_ULIMIT_CHECKS to false in your profile or solr.in.sh
Waiting up to 180 seconds to see Solr running on port 8983 [-]  
Started Solr server on port 8983 (pid=3054). Happy searching!

You can access the Solr application from the browse at : http://localhost:8983/solr/. The screenshot below shows the Solr application.

2.5 Apache Solr

Apache Solr merged into Lucene around 2010. Lucene was created by Doug Cutting in 1999. Solr was developed by Yonik Seeley at CNET. Solr had a cloud feature released in 4.0. Solr 6.0 supported parallel SQL queries. Solr is based on Lucene. It has REST API support. It has an inverted index feature to get documents for a query using the search word. The search word is entered by the user to link the documents to the word. Solr has the features such as support for XML/JSON/HTTP, recommendations, automatic load balancing, spell suggestions, autocompletion, geospatial search, authentication, authorization, multilingual keyword search, type ahead prediction, batch processing, streaming, machine learning models, high volume web traffic support, schema, schemaless configuration, faceted search, filtering, and cluster configuration.

2.6 Apache Solr – Multilingual example

To handle multiple languages, the core per language approach can be used in Apache Solr. Solr supports different languages. MultiCore approach is used as it is simple. It has minimal configuration effort. Maintenance can be an issue as the number of languages increase.

Let us look at an example with Solr fields for documents in english:documents in english

<add>
  <doc>
	<field name="id">1</field>
	<field name="title">Sherlock Holmes</field>
    <field name="content">This book consists of Holmes cases and how he solves them with Dr.Watson</field>
  </doc>
  <doc>
	<field name="id">2</field>
	<field name="title">Perry Mason</field>
    <field name="content">This book consists of Perry mason cases and how he solves them in a legal way. He works as a lawyer</field>
  </doc>
  <doc>
	<field name="id">3</field>
	<field name="title">Robin Crusoe</field>
    <field name="content">This book consists of Crusoe's adventures</field>
  </doc>
  <doc>
	<field name="id">4</field>
	<field name="title">Gulliver Travels</field>
    <field name="content">This book consists of Gulliver excursions and journeys</field>
  </doc>
  <doc>
	<field name="id">5</field>
	<field name="title">Alice's Adventures</field>
    <field name="content">This book consists of Alices adventures in the wonderland</field>
  </doc>
</add>

Let us look at the same in the french example below:documents in french

<add>
  <doc>
    <field name="id">1</field>
    <field name="title">Jules Verne</field>
    <field name="content">Voyage au centre de la terre, Jules Verne</field>
  </doc>
  <doc>
    <field name="id">2</field>
    <field name="title">La belle et la bete</field>
    <field name="content">La belle et la bete, Gabrielle-Suzanne Barbot de Villeneuve</field>
  </doc>
  <doc>
    <field name="id">3</field>
    <field name="title">La Cousine Bette</field>
    <field name="content">La Cousine Bette, Honoré de Balzac</field>
  </doc>
  <doc>
    <field name="id">4</field>
    <field name="title">VOYAGE AU BOUT DE LA NUIT</field>
    <field name="content">Voyage au bout de la nuit, Céline</field>
  </doc>
  <doc>
    <field name="id">5</field>
    <field name="title">Voltaire</field>
    <field name="content">Candide, Voltaire</field>
  </doc>
</add>

You can implement this by copying the directory example within solr installation and rename it as coreperlanguage. Ensure that it is a deep copy of the directory. Within the directory, remove the unused directories like example-DIH, multicore,example-schemaless, and others. Remove the directories under the solr folder except bin. You can copy the folders and files from the source code ($SOURCE_CODE) provided to solr. You can execute the commands below from the coreperlanguage directorySolr start output

cd $SOLR_INSTALL
cp -R example coreperlanguage
rm -r example-DIH
rm -r multicore
cd $SOLR_INSTALL/coreperlanguage
rm -r *
cp * $SOURCE_CODE/* .

Note that the core.properties is changed the name from collection to coreperlanguage directory. You can restart Solr from coreperlanguage folder by using the command below:Solr start command

cd $SOLR_INSTALL/coreperlanguage
java -jar start.jar

The output of the command is shown below:Solr start output
