Substring matching for Twitter mentions


#1

Is there any possible way to do substring matching for twitter mentions?

I know for twitter.user.screen_name it is possible to filter for all tweets from any author that includes a particular substring (such as “bob”)

However, I’m not too clear if that’s also possible for twitter.mentions. If it isn’t, is there any other way to filer tweets according to a substring in mentions?

Yes - substr is a valid operator for the twitter.mentions target.

There are also several regex operators, which may be useful for this: regex_partial and regex_exact
