[OASIS Issue Tracker] Updated: (ODATA-394) Introduce path segment /$all for search on service and entity container level

[OASIS Issues Tracker <workgroup_mailer@lists.oasis-open.org>]

     [ http://tools.oasis-open.org/issues/browse/ODATA-394?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Ralf Handl updated ODATA-394:
-----------------------------

    Proposal: 
Introduce symbolic resources

(a) service-root/$all
(b) service-root/Entity.Container/$all

that identify (a) the union of all entities in the service or (b) the union of all entities in the container.

These are of type Collection(Edm.EntityType) and allow $search plus all query options applicable to collections of entities.

> With ODATA-228 we introduced free-text search on service and entity-container level with the system query option $search.
> This simplistic approach has the drawback of making the resource type dependent on the presence or absence of the $search query option: if present, the URL identifies a collection of entities, if absent the service root identifies the service document and the entity containers identify the Cartesian product of their entity sets.
