Searching yahoo with selenium

[Truman]

The last time I was doing an automatization of search ( on google ) it was with bs4 and webbrowser only. Now I'm trying to use selenium first. So, I want to achieve this:
1. open a browser
2. open yahoo search page
3. search for term 'seleniumhq'
4. open first 5 results in 5 different tabs

in later stage when I improve the algorithm planning to bundle it into functions and with input() but first want my basic code to work. Help is appreciated.

code:

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
import bs4

browser = webdriver.Firefox()
browser.get('http://www.yahoo.com')
assert 'Yahoo' in browser.title

elem = browser.find_element_by_name('p') # find the search box
res = elem.send_keys('seleniumhq' + Keys.RETURN)

soup = bs4.BeautifulSoup(res.text, "html.parser")
linkElems = soup.select('a')
for link in linkElems:
	print(f'link: {link}')
numOpen = min(5, len(linkElems))
for i in range(numOpen):
	webbrowser.open(linkElems[i].get('href'))

browser.quit

error:

Error:
Traceback (most recent call last):
  File "C:\Python36\kodovi\sel4.py", line 12, in <module>
    soup = bs4.BeautifulSoup(res.text, "html.parser")
AttributeError: 'NoneType' object has no attribute 'text'

According to this res is nontype object. Don't know why and don't know how to make it type so that code can be fully conducted ( although not sure that the rest is good ).
