问题
Since Facebook introduced hashtags, I\'ve been interested in finding out more about them. Can someone point me in the direction of possibly tracking the hashtags similar to how twitter allows us access to pull hashtag data via their API. I can count mentions, get usernames, and the tweets. Has Facebook launched anything similar? I can\'t find any documentation online.

There is currently no API for the hashtags feature on Facebook
edit: there was however a public posts search function which will return some public posts with a certain hashtag if you use that hashtag as the search string in API version 1.0 - there is no equivalent in version 2.0 onwards
It ignores the # symbol in the matching though, so a search for '#omg' will find posts with 'omg' too.
See https://developers.facebook.com/docs/graph-api/using-graph-api/v1.0#search )

Facebook recently announced new tools for surfacing conversations with the launch of Public Feed API which :
displays a real-time feed of public posts for a specific word
Unfortunately, that tool is restricted to a small set of "trusted" users for now...
