Hi ,
I am a new elastic search user , I was going through the documentation of
percolator API. had couple of questions.
1. What is the use of this functionality in real world any example of its
usage.
2. generally we query and get relevant data and use the data. here we get
what query the data matches what's the use of it.

Hi,
you can start reading this
blog: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/blog/percolator/) .
These slides should be interesting as well, as they contain usecases for
the percolator: [https://speakerdeck.com/javanna/whats-new-in-percolator](https://speakerdeck.com/javanna/whats-new-in-percolator) .
One of the usecases is for instance to register users interests and be able
to notify users as soon as a new interesting document comes in. Users
interest would be represented as elasticsearch queries and stored in
elasticsearch. Each new document would be percolated in order to know which
users are interested in it, and notify them. This is pretty much an example
of the alerting usecase. You can find in the slides other two usecases for
the percolator though.
Cheers
Luca
