Sitecore
integration with Solr
Solr ?
Solr is highly reliable, scalable and fault tolerant, providing
distributed indexing, replication and load-balanced querying, automated
failover and recovery, centralized configuration and more. Solr powers the
search and navigation features of many of the world's largest internet sites.

Prerequisite
Software
·
solr-4.5.1.zip (Download from https://archive.apache.org/dist/lucene/solr/4.5.1/)
·
Sitecore 8.1
2.
Setup Solr
Instance
2.1 Download Solr
·
Download the Solr and extract it in one folder.
Ex : D:\SolrPOC\Solr\Solr-4.5.1\
·
Setup the Solr , Follow below link

2.2 Generate an XML Schema for Solr
You can modify an existing schema with the Generate the Solr
Schema.xml file tool. This tool automatically generates a basic schema and
ensures all the fields that Sitecore needs are present. You can add your own
fields to this schema, as long as you do not change the system index fields.
Follow below steps to generate the schema.xml file.
·
Login into Sitecore CMS instance
·
Click on Control Panel
·
In the Control Panel, INDEXING section ,click Generate the Solr Schema.xml file:
·
In the Source file field,
enter the path to the Solr schema that you want to use (schema.xml file present
inside D:\SolrPOC\Solr\Solr-4.5.1\\server\solr\configsets\basic_configs\conf).
·
In the Target file field,
enter the destination for the new schema file.
·
Click on Generate
button
·
Sitecore updates the schema.xml file and adds all the
necessary fields that it needs.
·
Keep newly generated schema file handy. We will use in step 2.3
Note : Create path folder on server where Sitecore is hosted.
2.3 Core folders Setup
·
Navigate to folder D:\SolrPOC\Solr\Solr-4.5.1\server\solr\configsets
and copy folder “basic_configs”
·
Paste this folder under D:\SolrPOC\Solr\Solr-4.5.1\server\solr\
·
Rename the folder as “sitecore_master_index”
·
Copy the generated file (schema.xml ) and paste to replace them in
D:\ \Solr-4.5.1\server\solr\sitecore_master_index\conf
·
Duplicate the “sitecore_master_index” folder and rename it as
“Sitecore_web_index”
·
Similarly duplicate the folder “Sitecore_master_index” and rename
it as “Sitecore_core_index”
Note: You must you use a separate core
for each index. Solr introduces the multiple core concept. When you
configure Solr, use the 64-bit version of the Java Virtual Machine (JVM) for
production servers. Solr allocates 512 MB of memory by default. If you require
Solr to have access to more memory you can adjust these limits when Solr starts
up.
2.
Apache Tika
configuration
Apache Tika detects and extracts metadata and text from different
file types (such as PPT, XLS, and PDF). It can take URL of documents also to
extract content.
Please follow below steps to enable Apache Tika in
Sitecore_Master_Index core.
It is required to be done only in CMS.
·
Copy dist and contrib folders from path D:\SolrPOC\Solr\Solr-4.5.1\
·
Paste these folders in D:\SolrPOC\Solr\solr-5.4.1\server\solr\sitecore_master_index\
·
Paste below lines after <luceneMatchVersion>5.4.1</luceneMatchVersion>
in D:\SolrPOC\Solr\Solr-4.5.1\server\solr\sitecore_master_index\conf\solrconfig.xml
<lib
dir="dist/" regex=".*\.jar" />
<lib dir="contrib/extraction/lib"
regex=".*\.jar" />
·
Copy below request handler configuration in D:\SolrPOC\Solr\solr-5.4.1\server\solr\sitecore_master_index\conf\solrconfig.xml
<requestHandler
name="/update/extract"
startup="lazy"
class="solr.extraction.ExtractingRequestHandler" >
<lst name="defaults">
<str
name="lowernames">true</str>
<str
name="fmap.content">mediacontent_t</str>
<str
name="defaultField">text</str>
<str
name="_datasource">sitecore</str>
<bool
name="ignoreTikaException">true</bool>
</lst>
</requestHandler>
·
Restart the Solr service from Window service.

Integrating
Solr with Sitecore
3.1 Disable / Delete Lucene and enable Solr configuration files
Your website Include folder contains several configuration files. Lucene search
is enabled by default. If you want to use Solr, you normally disable the Lucene
search config files and enable the Solr config file .This enables Solr
integration and gives you access to all the Solr specific configuration
settings.
To switch configuration files so that Solr is enabled and Lucene
is disabled:
·
Navigate to the website Include folder: \website\App_Config\Include\
and search for Lucene
·
Disable all file by adding .example
to the file name extension.
·
Search for Solr and enable all files by removing .example from file name extension.
·
By default below index files present in include folder :
Sitecore.ContentSearch.Solr.Index.Master.config
Sitecore.ContentSearch.Solr.Index.Web.config
Sitecore.ContentSearch.Solr.Index.Core.config
·
If you want to create another index then copy and paste file and
rename as : Sitecore.ContentSearch.Solr.Index.NA.Master.config
Sitecore.ContentSearch.Solr.Index.NA.Web.config
Sitecore.ContentSearch.Solr.Index.EU.Master.config
Sitecore.ContentSearch.Solr.Index.EU.Web.config
·
Enter the index name accordingly : ex : <index id="eu_master_index"
·
Set Crawler root and database accordingly.
<crawler
type="Sitecore.ContentSearch.SitecoreItemCrawler,
Sitecore.ContentSearch">
<Database>master</Database>
<Root>/sitecore/content/2_EU</Root>
</crawler>
Note:
These config files only require in CMS server.
3.2 Solr Specific Settings
The following Solr specific settings can be found in the Sitecore.ContentSearch.Solr.DefaultIndexConfiguration.config
file
·
Specifying a Solr Service
Address :
This setting tells Sitecore where the Solr server is located.
Sitecore appends the core name so only the base address needs to be supplied.
<setting name="ContentSearch.Solr.ServiceBaseAddress"
value="http://localhost:8983/solr" />
·
Enabling a Search Provider
:
This setting tells Sitecore that Solr is enabled and so attempts
to connect to the Solr server the next time the index is accessed.
<setting name="ContentSearch.Provider"
value="Solr" /> (Default: “Lucene”)
·
Maximum
Number of Search Result
This is a global setting found in the Sitecore.ContentSearch.config file.
This setting contains the maximum number of documents to retrieve
on a single request if a limit has not been specified in the query, for
example, Take(10).
<setting name="ContentSearch.SearchMaxResults"
value="500" />
·
Enabling
Batch Mode
When an item is indexed, the composed document is saved to the
search index. When the default Lucene provider is enabled then each write is
being flushed to a file on the local disk. When a document is written using the
Solr provider the update has to travel over a network.
When an index is rebuilt a large number of document updates are
created, this could result in a lot of network traffic which is not very
efficient. Therefore using batch can help to optimize the update process as
your indexes grow in size.
<setting
name="ContentSearch.Update.BatchModeEnabled" value="true"
/> <setting
name="ContentSearch.Update.BatchSize" value="500" />

Sitecore
Indexing
·
Login to Sitecore and go to Control
Panel
·
Click on Indexing Manager
·
Select index name to
rebuild
·
Click on Rebuild and wait until the indexing is completed.
·
After indexing completed, browse below url and check records are
there are not http://localhost:8983/solr/sitecore_master_index/select?q=*
·
Similarly repeat above steps to rebuild sitecore_web_index and sitecore_core_index.
