Bonus, if we find native speakers to help us:

• Support Greek: #1287842: Support for Solr 3.x language specific filters (Greek, ...) (Greek-speaking users willing to help: klonos)
• Support Chinese: #1081850: Chinese language support
• ...

Notes:

• The generic part of config file generation has been moved to a separate module named Apache Solr Config Generator
• A bug fix patch for Apache Solr Search is required: #1702788: content and teaser are empty if node->language is not default (done)
• A bug fix patch for Apache Solr Search is required: #1759004: apachesolr_search_custom_page_search_form_submit() kills all $_GET parameters (done)
• We committed some patches to the variable module. Therefore you have to use the current dev version of Variable 7.x-2.x until 7.x-2.2 will be released.
• For entity translation a core patch might be needed http://drupal.org/files/d7-1823306-do-not-test.patch The issue is currently filed against drupal 8: #1823306: Language code is missing from $context when hook_field_attach_view_alter() is invoked from field_view_field()
• These patches against the apachesolr module are essential to run the latest dev version of Apache Solr Multilingual: #1918012: Solr query needs to be aware of more context such as Search Page ID, #1918030: Allow contrib modules to add custom settings to search pages, #1896470: Integrate Apache Solr Common Configurations for Solr 3.x and 4.x (Highlighting broken) (done)
• These patches against the apachesolr module improve the result: #1970648: sort block breaks multilingual sites, #1946132: ERROR: Warning: implode() [function.implode]: Invalid arguments passed in theme_apachesolr_search_snippets() (line 1708 of...)

Testing:

• Read through my slides to get a basic understanding of language specific full text searching: Language-Specific and Multilingual Full-Text Searching
• Install Apache Solr Multilingual and Apache Solr Config Generator and (some of) their sub-modules (in various order)
• Configure Apache Solr Multilingual in different ways and try the search
• Enable / disable different languages
