[Search] New Component and Contracts

[JoshuaEstes]

Many apps have some type of search, this could be a basic search on a database field or using some type of backend like solr. Algolia and AWS CloudSearch could also be some solutions.

The new component would provide the ability to swap out different backends and the contracts would allow others to create implementations.

One idea would to be able to chain different search backends together, for example, multiple database backends could search many different tables and columns and provide a global search. Add in some of the other backend and this could be pretty powerful.

$search = new Search($backend);
$results = $search->query('search term');

Possible Interfaces

• SearchInterface (Primary interface that is used)
• QueryInterface (sent to the backend)
• ResultInterface (returned from the backend)
• ResultSetInterface (contains many ResultInterfaces)
• BackendInterface (Database, Mock, Null, Algolia, etc)
• FacetAware, HighlightAware, etc. (Different backends support different features)

Compatible with components: logger, cache, links

Can use the Pager Component for results
