Collections in Request Parameters are OR Related
When you specify multiple collections through the collection request parameter of the following methods, they are now OR related:
GET and POST /v1/search
GET and POST /v1/qbe
GET and POST /v1/values/name
The new behavior is consistent with the semantics of cts:collection-query and the structured query collection-query.
To get AND semantics, construct your own and-query of collection URIs as part of a structured or combined query, or by defining a constraint in your query options.
The new behavior differs from previous behavior in the following way:
In MarkLogic 8.0-6, the GET methods applied AND semantics to multiple collection parameters, while the POST methods applied OR semantics.
In MarkLogic 8.0-5 and earlier, both GET and POST methods applied AND semantics to multiple collection parameters.
