How to set up NiFi to receive posts from Facebook that contains certian words?

[#1]

I am new to NiFi Flow and I am currently trying to pull information from Facebook. I want to be able to pull posts that contain a specific word that I initially set. For example, I want all posts that contain the letters "butter" in real time. Then I want to store it in HDFS. Very much like the Twitter Grab Garden Hose processor but for Facebook.

What are some of the processors that I need to use to make this happen and what other information would I need to move forward?

Thanks in advance.
