This checks the steam search api for keywords. Feed it with a wordlist (a list of words, each keyword (can be space seperated) in a new line). Should work with \c, \c\r and \r). Needs Requests, works best with Python3.

steamfinder.py

import requests
app_id = 0  # enter some AppID first.
url = "http://store.steampowered.com/actions/clues"
with open('wordlist.txt' as 'r') as f:
  words = f.readlines()

// Go through all words - if the last character is a newline, truncate
words = [word[:-1] for word in words if word[-1] is '\n']

for word in words:
  response = requests.get(url=url, params={'key': word}, headers={"Referer": "app/{}".format(app_id)})
  if not response.status_code is 200:
    print("Failed request on: {}".format(word))
  if not response.json() is "[]":
    print("HIT ON:")
    print(response.json())
print("Done.")
