search_api_solr 8.x-1.0-rc2

This is the second release candidate of the Search API Solr Search 8.x-1.0. The minimum "officially supported" Solr version is still 4.5.1. The latest supported Solr version is 6.4.2.
Any newer Solr version might work for you, but there is a known issue at the moment, #2869529: Autocomplete (and spell checking) is broken on Solr 6.5.x, Solr 6.6 will solve the issue.

This release only works in combination with search_api 8.x-1.1!

The most important change that happened during the beta phase was the introduction of SolrConnector classes that allow Solr providers to do their specific adjustments without hacking the Solr backend class anymore. Local and standard installations will be supported by this module out of the box. An corresponding upgrade path is included. For other installations you can check these issues:

• Acquia: #2817387: Provide a proper SolrConnector plugin
• Pantheon: #2821770: Pantheon Connector: Plan for next release?
• Open Solr: #2819821: OpenSolr Support

If you update an existing installation, the first thing you should do is to deploy the latest Solr config files from the module's solr-conf folder and afterwards delete all the data from the index and start a re-indexing process!

The basic API is considered complete now and the essential stuff works very well, but we still have incomplete features which will be addressed after the final release of 1.0:

• #2682347: Expose solr-only fields to views
• #2831842: Prepare usage of Solr's suggester component for autocomplete suggestions and re-enable multiple "indexes" per Solr Core later
• #2873227: Implement Solr specific views cache backend
• #2864967: Fix multisite search/multiple indexes on one core, tho it might break spell checking, autocomplete and suggesters
• #2863611: Support range facets
• ...
