.where selector is mandatory when using .select or .partialIndex

[paultranvan]

When a query is run without a selector and sort, the Collection.all will be used: https://github.com/cozy/cozy-client/blob/master/packages/cozy-client/src/StackLink.js#L86-88.
For instance:

client.find(Q(doctype).partialIndex({trashed: false}).fields(['trashed', 'dir_id', 'name']))

Furthermore, a sort cannot be used without a selector according to #405

When the Collection.all is used, some query options cannot work such as .partialIndex or .select, as the _all_docs API will be used , that does not support such features.

This issue still exists for contacts because of: https://github.com/cozy/cozy-client/blob/master/packages/cozy-stack-client/src/ContactsCollection.js#L13
If a query has no selector but a partialFilter, this will fail, as found by @cballevre

Petit souci également avec une requête de ce type

export const buildContactsQuery = (enabled = true) => ({
  definition: () =>
    Q(CONTACTS_DOCTYPE)
      .select([
        'name',
        'displayName',
        'fullname',
        ...
      ])
      .limitBy(1000),
  options: {
    as: CONTACTS_DOCTYPE,
    fetchPolicy: defaultFetchPolicy,
    enabled
  }
})

génère l'erreur suivante :

error: "missing_required_key"
ok: false
reason: "Missing required key: selector"
status: "400"

l'astuce pour l'instant consiste à rajouter _id dans le select et un .where({ _id: { $gt: null } })

CouchDB expect a mandatory selector for mango queries: https://docs.couchdb.org/en/stable/api/database/find.html#db-find

Up, un nouveau souci trouvé aujourd'hui, avec cette définition :

Q(GEOJSON_DOCTYPE)
    .indexFields(['cozyMetadata.sourceAccount'])
    .sortBy([{ 'cozyMetadata.sourceAccount': 'desc' }])
    .limitBy(1000)

Elle génère la même erreur que ci-dessus

error: "missing_required_key"
ok: false
reason: "Missing required key: selector"
status: "400"

Elle reste contournable avec l'ajout d'un .where({})
