Rule matcher plugins

This guide introduces you how to configure Rule matcher plugins.
These plugins allow to define if a product should be sent according to its content and metadata.

Here is the list of documented plugins:

• Default Rule Matcher allows sending a notification if its content json properties match specific values
• Lucene Rule Matcher allows sending a notification if its content or its metadata match given Lucene expressions

To import your plugin configurations to Notifier, you need update microservice configuration using REST API
