How to setup Solr with Oscar

Apache Solr is Oscar’s recommended production-grade search backend. This how-to describes how to get Solr running, and integrated with Oscar. The instructions below are tested on an Ubuntu machine, but should be applicable for similar environments. A working Java or OpenJDK installation are necessary.

Installing Solr

You first need to fetch and extract Solr. The schema included with Oscar is tested with Solr 4.7.2:

$ wget
$ tar xzf solr-4.7.2.tgz

Integrating with Haystack

Haystack provides an abstraction layer on top of different search backends and integrates with Django. Your Haystack connection settings in your for the config above should look like this:

    'default': {
        'ENGINE': 'haystack.backends.solr_backend.SolrEngine',
        'URL': '',
        'INCLUDE_SPELLING': True,

Build Solr schema

Next, replace the example configuration with Oscar’s.

$ ./ build_solr_schema > solr-4.7.2/example/solr/collection1/conf/schema.xml

You should then be able to start Solr by running:

$ cd solr-4.7.2/example
$ java -jar start.jar

Rebuild search index

If all is well, you should now be able to rebuild the search index.

$ ./ rebuild_index --noinput
Removing all documents from your index because you said so.
All documents removed.
Indexing 201 Products
Indexing 201 Products

The products being indexed twice is caused by a low-priority bug in Oscar and can be safely ignored. If the indexing succeeded, search in Oscar will be working. Search for any term in the search box on your Oscar site, and you should get results.
