I'm aware that Answer bot suggests articles based on the first 75 words of the article (or it weighs it more heavily as compared to the rest of the article).
I know there's triggers as well that one can set up, but I wanted to find out if I can do triggers based on words that come from the subject line when customers submit helpdesk tickets. 

I guess what I'm thinking of is 'feeding' answer bot, but I know that can't be done, just want to see if there are any other suggestions available.
