QA Note

• When the post processors are registered properly, you should see the following log messages upon executing a search from the home page after you configured an "INFO" log level for category com.liferay.blade.samples.indexerpostprocessor (the test jar attached already contains a module-log4j.xml to configure INFO logging for the bundle):

  12:57:45,094 INFO  [http-nio-8080-exec-10][UserEntityIndexerPostProcessor:89] postProcessSearchQuery

• On DXP you may get the following NullPointerException instead of error:
