Adds support for fulltext search engines like Sphinx and Solr to SilverStripe CMS.

• Hamish Friedlander <hamish (at) silverstripe (dot) com>

• SilverStripe 3.1+
• (optional) silverstripe-phockito (for testing)

See docs/en/index.md

• Get rid of includeSubclasses - isn't actually used in practice, makes the codebase uglier, and ClassHierarchy can be used at query time for most of the same use cases

• Fix field referencing in queries. Should be able to do $query->search('Text', 'Content'), not $query->search('Text', 'SiteTree_Content') like you have to do now

  • Make sure that when field exists in multiple classes, searching against bare fields searches all of them

  • Allow searching against specific instances too

• Make fields restrictable by class in an index - 'SiteTree#Content' to limit fields to a particular class, maybe 'Content->Summary' to allow calling a specific method on the field object to get the text

• Allow following user relationships (Children.Foo for example)

• Be clearer about what happens with relationships to stateful objects (e.g. Parent.Foo where Parent is versioned)

• Improvements to SearchUpdater

  • Make it work properly when in-between objects (the A in A.B.Foo) update

  • Allow user logic to cause triggering reindex of documents when field is user generated

• Add sphinx connector

• Add generic APIs for spell correction, file text extraction and snippet generation

• Better docs
