ArangoDB also allows removing, replacing, and updating documents based on an example document. Every document in the collection will be compared against the specified example document and be deleted/replaced/ updated if all attributes match.
These method should be used with caution as they are intended to remove or modify lots of documents in a collection.
All methods can optionally be restricted to a specific number of operations. However, if a limit is specific but is less than the number of matches, it will be undefined which of the matching documents will get removed/modified. Remove by Example, Replace by Example and Update by Example are described with examples in the subchapter Collection Methods.
