/**
 * Creates a query to retrieve a list of collections.
 *
 * The `queryCollections()` method builds a query to retrieve a list of collections and returns a `CollectionsQueryBuilder` object.
 *
 * The returned object contains the query definition, which is used to run the query using the [`find()`](https://dev.wix.com/docs/sdk/backend-modules/portfolio/collections/collections-query-builder/find) method.
 *
 * You can refine the query by chaining `CollectionsQueryBuilder` methods onto the query. `CollectionsQueryBuilder` methods enable you to filter, sort, and control the results that `queryCollections()` returns.
 *
 * `queryCollections()`  runs with the following `CollectionsQueryBuilder` defaults which you can override:
 *
 * + [`limit(100)`](https://dev.wix.com/docs/sdk/backend-modules/portfolio/collections/collections-query-builder/limit)
 * + [`ascending('_id')`](https://dev.wix.com/docs/sdk/backend-modules/portfolio/collections/collections-query-builder/ascending)
 *
 * The following `CollectionsQueryBuilder` methods are supported for `queryCollections()`. For a full description of the operations object, see the object returned for the [`items`](https://dev.wix.com/docs/sdk/backend-modules/portfolio/collections/collections-query-result/items) property in `CollectionsQueryResult`.
