 If needed, you can abort a bulk operation at any time. The bulk helper returns a https://promisesaplus.com/[thenable], which has an `abort` method.
 
 NOTE: The abort method will stop the execution of the bulk operation, but if you are using a concurrency higher than one, the operations that are already running will not be stopped.

 If you are creating multiple msearch helpers instances and using them for a limitied period of time, remember to always use the  `stop` method once you have finished using them, otherwise your application will start leaking memory.
