I need to get tweets that contain at least of the following hashtags: #EUwahl #Euwahlen #Europawahl #Europawahlen. This means, I am looking for tweets containing at least one of those hashtags but they can also contain more of them. Furthermore, in each of these tweets one out of seven specific user (eg @AfD) must be mentioned as well in the tweet.
So far I only know how to search Twitter for one hashtag only or several ones. Meaning, I am familiar with the operator and using a + between the hashtags but not with the operator for or.
This is an example of a code I have used so far to do any searches in Twitter:
euelection <- searchTwitter("#EUwahl", n=1000, since = "2019-05-01",until = "2019-05-26")
