2. Standard moodle theme doesn't have any renderer file so you may simply copy this to your theme directory.

3. Rename renderer class name according to your theme name.

for example if you are using theme 'clean'. then rename the class names to 'theme_clean_core_renderer' & 'theme_clean_core_course_renderer'.

Installing Solr & placing the plugin Schema

Download the latest Solr 4.4.0 release from: http://lucene.apache.org/solr/

Unpack the tarball somewhere not visible to the web (not in your apache docroot and not inside of your moodle directory).

The Solr download comes with an example application that you can use for testing, development, and even for smaller production sites. This application is found at apache-solr-4.4.0/example.

Move apache-solr-4.4.0/example/solr/collection1/conf/schema.xml and rename it to something like schema.bak. Then move the schema.xml that comes with moodle course search admin tool plugin to take its place.

Similarly, move apache-solr-4.4.0/example/solr/collection1/conf/solrconfig.xml and rename it like solrconfig.bak. Then move the solrconfig.xml that comes with the moodle course search admin tool plugin to take its place.

Finally, move apache-solr-4.4.0/example/solr/collection1/conf/protwords.txt and rename it like protwords.bak. Then move the protwords.txt that comes with the moodle course search admin tool plugin to take its place.

Make sure that the conf directory includes the following files - the Solr core may not load if you don't have at least an empty file present: solrconfig.xml schema.xml elevate.xml mapping-ISOLatin1Accent.txt protwords.txt stopwords.txt synonyms.txt

Now start the solr application by opening a shell, changing directory to apache-solr-4.4.0/example, and executing the command java -jar start.jar

Test that your solr server is now available by visiting http://localhost:8983/solr/admin/

Testing with ping to solr

3. Click on "Check Solr instance Setting". if it Shows ping successful(with an success image). Now click save changes.

4. Now click on "Index courses" to index all the courses. After successful indexing. It will come up with a success image.
