Intro

SortClauses are the sorting options for Content and Location Search in "Platform stack", for generic use of API Search see Search Criteria and Sort Clauses

SortClause consists of two parts just like Criterion and FacetBuilder:

• The API Value: "SortClause"
• Specific handler per SearchEngine: "SortClausesHandler"

The SortClause represent the value you use in the API, while SortClauseHandler deals with the business logic in the background translating the value to something the Search engine can understand.

Common concepts for all Sort Clauses 

For how to use each and every SortClause see list below as it depends on the SortClause Value constructor, but in general you should be aware of the following common concept:

• sortDirection: The direction to perform the sort, either Query::SORT_ASC (default) or Query::SORT_DESC

List of Sort Clauses 

The list below reflects Sort Clauses available in eZ\Publish\API\Repository\Values\Content\Query\SortClause namespace (it is also possible to make custom SortClause):

Location\Depth	?sortDirection
Location\Priority	?sortDirection
Location\Visibility	?sortDirection

Only for ContentSearch
