I am trying to find the best way to create a quick filter for a board using a word in summary

I am trying to create a quick filter for my Jira board that will only display tickets that have a specified word found in the summary section of the ticket. I have tried summary ~ Word but that is not filtering out any Ticket without Word in summary. 

So how do I write a jql that will look for specific words in summary? If I could use contains it would look like this summary contains "Word" and I would only see tickets with Word in the summary.

What's the real JQL you're using and what other issue summaries show up despite it?

 

~ is essentially "contains" (although there are minute differences) so I'm asking for the real values as the behaviour you describe should not be happening;
