Integrating Solr with liferay in windows

1. Download the Solr-4.10.2 release from Solr.
2. Unzip .zip in some location(E:\Liferay\Integrations).It is  Slor home directory.
3. Copy the solr-4.10.2.war from Solr home dirctory\dist (E:\Liferay\Integrations\solr-4.10.2\dist) and paste it into E:\Liferay\Integrations\solr-4.10.2\example\solr.
4. Open up the E:\Liferay\Integrations\solr-4.10.2\example\solr\collection1\conf\solrconfig.xml.   


Replace
<dataDir>${solr.data.dir: ./solr/data}</dataDir>
by following
<dataDir>${solr.data.dir:E:\Liferay\Integrations\solr-4.10.2\example\solr\collection1\data}</dataDir>

  Note: The dataDir can also be temporarily overridden with the JAVA_OPTS environment variable  prior to starting Tomcat
                            JAVA_OPTS="-Dsolr.data.dir=/Solr_Home/solr/example/solr/data"





It is recommended to run the Solr instance on seperate tomcat instance other than liferay tomcat.
So for seperate tomact for solr download  tomcat zip
It is tomcat home folder(E:\Liferay\solr\apache-tomcat-7.0.50).
In the tomcat home folder under config create directory tomcathome/Catalina/localhost,Under this directory create solr.xml file and copy the following content into the file and save it.



<Context docBase="E:/Liferay/Integrations/solr-4.10.2/example/solr/solr-4.10.2.war" debug="0" crossContext="true">
<Environment name="solr/home" type="java.lang.String" value="E:\Liferay\Integrations\solr-4.10.2\example\solr" override="true"/>
</Context>





Copy the jars from solr/example/lib/ext into your container's main lib directory. These jars will set up SLF4J and log4j. (E:\Liferay\solr\apache-tomcat-7.0.50\lib)
Download the commons-logging jar also and paste in E:\Liferay\solr\apache-tomcat-7.0.50\lib.
Now start tomcat and check that it is running without any error or not.

                                                  Integrating Solr plugin with Liferay

Openup the Liferay_Home/apache-tomcat-7.0.50/webapps/solr-web/WEB-INF/classes/META-INF/solr-spring.xml
