This is a recipe to set up and configure SOLR in a django-haystack environment.

A basic buildout configuration using this recipe looks like this (using djc.recipe):

[buildout]
eggs = django-haystack
parts =
    solr-download
    solr
    django

[django]
recipe = djc.recipe
project = dummydjangoprj

[solr-download]
recipe = gocept.download
url = http://mirror.nohup.it/apache/lucene/solr/3.4.0/apache-solr-3.4.0.tgz
strip-top-level-dir = true

[solr]
recipe = abstract.recipe.haystack-solr
solr-location = ${solr-download:location}
django-settings-file = ${django:location}/settings.py
eggs =
    ${buildout:eggs}
    ${django:project}

This will download SOLR and create an executable at bin/solr. The name of the script is the name of the section.

To test the setup run bin/solr fg and check the console output. By default this will run a Jetty server on port 8080. The SOLR instance is accessible in a browser at http://127.0.0.1:8080/solr/.

When SOLR is started the first time, django-haystack is invoked to create the SOLR schema: the same will happen (overwriting any existing schema) if you run bin/solr reset.

SOLR will write all its log files into var/solr/log. All its configuration including jobs and past runs will go into var/solr/data. The directory name in var will have the name of the recipe section.

The recipe supports the following options:

eggs

Optional. The eggs the solr script should load. Since django-haystack is invoked, it must be atleast all the eggs that are necessary to run Django management commands.

django-settings

If your Django settings are in a module in sys.path, put here the module name. Either this or django-settings-file should be specified.

django-settings-file

If your Django settings are in a file not in sys.path, put here the file name. Either this or django-settings should be specified.

solr-location

The location of the part where the SOLR distribution has been downloaded.

solr-config

Optional. The file name containing the SOLR config (solrconfig.xml).

java-opts

Optional. Parameters to pass to the Java Virtual Machine (JVM) used to run Jetty. Each option is specified on a separated line. If you run into memory problems it's typical to pass:

[solr]
...
java-opts =
  -Xms512M
  -Xmx1024M
...

java-args

Optional. Extra arguments to pass to the Java Virtual Machine (JVM): this are typically all the parameters you'd pass after the jar file.

initialization

Optional chunk of code that is needed prior to Django bootstrapping.

environment-vars

Environment variables needed prior to Django bootstrapping.
